Now what?

That is the question placed most prominently in the minds of Vancouver Canucks coach Alain Vigneault and Montreal Canadiens coach Jacques Martin after having to change goaltenders in Monday's Stanley Cup Playoff games.

For sure, the switch from Jose Theodore to Semyon Varlamov paid off for Washington coach Bruce Boudreau Monday as the awakened Capitals pounded three goals past Jaroslav Halak in Game 3.

With the Canadiens absorbing a 5-1 loss to fall behind in the series, 2-1, Martin now faces the dilemma of going back to Halak, his bread-and-butter down the stretch, or stick with Carey Price, who entered Monday's game in the second period.

In Vancouver, the decision seems much clearer for the Canucks. Roberto Luongo is the team captain and go-to guy, so returning him to the net for Game 4 against the Los Angeles Kings seems the only logical move.

It is the game within the game in these playoffs, how best to marshal your goaltending, and it is a high-risk, high-reward gambit.

Martin explained after the Game 3 loss that he pulled Halak because he was trying to swing the momentum in the game. That worked in Game 2 for the Caps, when Boudreau benched Theodore for Varlamov.

"If you look at the first goal tonight, it's a shorthanded situation where they get a 2-on-1 and our defenseman backs into him and he doesn't have a chance," Martin told NHL.com's Dan Rosen, explaining Boyd Gordon's goal off his own rebound just 1:06 into the second period. "I think (Halak) played a strong first game of the series and tonight he made some good saves in the first period when he had to. In the second when we lost our momentum they capitalized."

Halak gave up three goals on four shots within a span of 7:27 in the second period. Making matters somewhat worse for the Canadiens was Alex Ovechkin's pre-game assertion that the Caps had rattled Halak. Now, Martin must mull returning Halak to the pressure cooker knowing another flat performance means a 3-1 deficit to the Caps.

"I think we'll meet and analyze the game," Martin told Rosen. "When you look at it, it's probably 12 minutes of bad play that cost us the game. There are some things that we did that were good, but it's one game and we have to be prepared to battle Wednesday."

Against the Kings Monday night, Luongo allowed 4 goals on 16 shots, and three of the goals came on the power play. Tough to blame a goalie facing a power play, but an admittedly bad goal by Brad Richardson made it 4-1 for the Kings and Luongo's night was over.

"I don't know. It was kind of a messed-up play," Luongo told NHL.com's Dave Lozo of the fourth goal. "Totally my fault. That's probably the one goal I'd like to have back there."

"I know he's going to bounce back," Kings coach Terry Murray said of Luongo. "I know Luongo. We traded for him when I was (coaching) in Florida. I know his character. He's going to bounce back with his 'A' game. And we're going to have to be prepared for it."

Boudreau's decision to yank Theodore in Game 2 started the ball rolling on coach's going to the bullpen. Boudreau said he fully expected to have to go to both goaltenders in the playoffs, so making the move in Game 2 wasn't a problem, or unexpected.

"I think we said before the series started if we are going to go anywhere we would probably have to use both goalies," Boudreau said. "I'm sure we're still going to use both goalies whether (Varlamov) plays Monday or Jose plays Monday. I think they are both going to play again. That's why we need to keep them sharp."

Boudreau said Theodore's professionalism makes his decision easier.

"I don't think he's a guy who is going to outwardly sulk," Boudreau said. "He's a professional and he'll work at it. His lows are followed by good highs and his highs are followed by lows and that's just been his nature."

Prior to the playoffs, NHL.com's John McGourty analyzed the backup situation for each of the 16 teams in the Stanley Cup Playoffs. The player records below show the number of games played, wins-losses-OT/shootout losses, shutouts, goals-against average and save percentage. In the case of some older veterans, their records show wins-losses-ties-OT/shootout losses. Here is a refresher on the goalie tandems for the 16 teams contesting the 2010 Stanley Cup Playoffs:

Eastern Conference

Washington Capitals

Jose Theodore

2009-2010: 47g, 30-7-7, 1, 2.81, .911

NHL Career: 548g, 245-221-30-22, 29, 2.68, .908

Stanley Cup Playoffs: 49g, 19-27, 1, 2.79, .913

Comment: Theodore, 33, is the 2002 Hart and Vezina Trophy winner. He went 20-0-3 since Jan. 13 with a 2.58 goals against average and a .922 save percentage to recapture the job he lost in Game 1 of last year's playoff series against the Rangers.

Semyon Varlamov

2009-2010: 26g, 15-4-6, 2, 2.55, .909

NHL Career: 32g, 19-4-7, 2, 2.52, .911

Stanley Cup Playoffs: 13g, 7-6, 2, 2.53, .918

Comment: Varlamov, 21, was Washington's first-round pick in 2006. He was spectacular for 15 games at the end of last season, going 4-0-1 at the end of the regular season, beating the New York Rangers in seven games and holding the Penguins down for the first three games of their second-round series before giving up 19 goals in the final four games. He was the Washington starter at the beginning of this season, but developed groin problems in December and lost his job to Theodore.

Montreal Canadiens

Jaroslav Halak

2009-2010: 45g, 26-13-5, 5, 2.40, .924

NHL Career: 101g, 56-34-7, 9, 2.62, .919 

Stanley Cup Playoffs: 3g, 0-1

Comment: Halak, 24, was the Canadiens' best player this season and the biggest reason the No. 8 seed is in the playoffs by one point over the Rangers. Halak became the No. 1 goalie at midseason.

Carey Price

2009-2010: 41g, 13-20-5, 0, 2.77, .912

NHL Career: 134g, 60-48-12, 4, 2.73, .912

Stanley Cup Playoffs: 15g, 5-10, 2, 3.11, .895

Comment: Price, 22, was Montreal's first-round pick in 2005. He played 26 of the first 36 games before encountering groin problems in December that lasted into February. He played only nine of the final 36 games.

New Jersey Devils

Martin Brodeur

2009-2010: 77g, 45-25-6, 9, 2.24, .916

NHL Career: 602g, 324-105-29, 110, 2.21, .914

Stanley Cup Playoffs: 176g, 98-79, 23, 1.98 GAA, .922

Comment: Brodeur, 37, is one of the best, if not the greatest goalie in NHL history. The Devils' first-round pick in 1990 has three Stanley Cups, may get his fifth Vezina Trophy this year, five Jennings Trophies, and has been named to seven NHL All-Star Teams. The 1994 Calder Memorial Trophy winner holds the NHL record of 110 shutouts, better than once every six games. A year after missing 50 games with an elbow injury, he tied the second-highest games-played total in his career.

Yann Danis

2009-2010: 12, 3-2-1, 0, 2.05, .923

NHL Career: 49g, 16-21-4, 3, 2.69, .912

Stanley Cup Playoffs: None

Comment: Danis, 28, has followed the route that NHL goalies pursued in the old days, tested and toughened for years in the minors. Until a year ago, he toiled in obscurity, except for a phenomenal senior year (2004) at Brown where he swept the ECAC trophy table and was named an All American. He has 286 minor-league games experience and his record this season shows he can come off the bench and win.

Philadelphia Flyers

Brian Boucher

2009-2010: 33g, 9-18-3, 1, 2.76, .899

NHL Career: 280g, 101-121-30-10, 17, 2.72, .900

Stanley Cup Playoffs: 22g, 11-8, 1, 2.06, .916 save percentage.

Comment: Boucher, 33, is the last man standing after Ray Emery, Michael Leighton and Johan Backlund were injured while starting in front of him. The Flyers' first-round pick in 1995, Boucher was given the No. 1 job when Emery underwent surgery in December, but Boucher had a finger crushed by a shot and surrendered the job to Leighton. He became the starter again when Leighton was hurt on March 16 and went 5-6-2. This is the only first-round playoff series this year matching starting goalies who were their team's first-round draft picks. The Washington-Montreal series is the only one with two first-round picks of their current teams sitting on the bench.

Johan Backlund

2009-2010: 1g, 0-1-0, 0, 3.00, .917

NHL Career: 1g, 0-1-0, 0, 3.00, .917

Stanley Cup Playoffs: None

Comment: Backlund, 28, has played part of one NHL game and has never played in the playoffs. He's been troubled by groin problems this season. Backlund was an excellent goalie in Sweden, an All-Star in 2007 and their goalie at the World Championships that year. He played well for the AHL Adirondack Phantoms this year.

Buffalo Sabres

Ryan Miller

2009-2010: 69g, 41-18-8, 5, 2.22, .929

NHL Career: 333g, 187-104-1-33, 17, 2.57, .914

Stanley Cup Playoffs: 34g, 20-14, 1, 2.40, .915

Comment: Miller, 29, led the league in goals-against average and save percentage until late in the season when Rask played enough games to qualify. He finished second in both categories. Buffalo's fifth-round pick in 1999 is widely regarded as the goalie most capable of "stealing" a game his team otherwise couldn't win. 

Patrick Lalime

2009-2010: 16g, 4-8-2, 0, 2.81, .907

NHL Career: 437g, 200-169-32-16, 35, 2.57, .905

Stanley Cup Playoffs: 41g, 21-20, 5, 1.77, .926

Comment: Lalime, 35, was one of the NHL's top goaltenders when he played for Ottawa from 1999-2004. Lalime struggled for victories during the regular season, but his internal numbers (GAA and save percentage) were better than his results. Sometimes a team just plays better in front of one goalie than another. When he's in shutout mode, once in every eight playoff games, it's lights out.

Boston Bruins

Tuukka Rask

2009-2010: 45g, 22-12-5, 5, 1.97, .931

NHL Career: 50g, 25-13-6, 6, 2.01, .930

Stanley Cup Playoffs: None

Comment: Rask, 23, was Toronto's first-round pick in 2005. He was acquired in a deal for Andrew Raycroft the next season. Rask had two solid seasons at Providence and earned the backup job at training camp. He started only 17 of the first 45 games but played 25 of the last 34. He is very well positioned and quick with his glove, feet and body. He dropped too many shots in the games I saw but it never seemed to cost him.

Tim Thomas

2009-2010: 43g, 17-18-8, 5, 2.56, .915

NHL Career: 262g, 126-91-35, 17, 2.61, .918

Stanley Cup Playoffs: 18g, 10-8, 1, 2.16, .926

Comment: Thomas, 35, didn't secure an NHL job until he was 31, playing college, European and minor-league hockey. He's the only goalie in the 2010 Stanley Cup Playoffs to have played in the ECAC, IHL, ECHL, AHL, Finnish and Swedish leagues. Thomas won the 2009 Vezina Trophy, but lost his job this season to a goalie, Rask, that experts have long thought will be one of the really great ones. Thomas was outstanding in the 4-3 shootout win last Sunday against the Capitals in what amounted to a shooting gallery as Capitals chased personal seasonal goals.

Pittsburgh Penguins

Marc-Andre Fleury

2009-2010: 67g, 37-21-6, 1, 2.65, .905

NHL Career: 302g, 148-106-2-30, 16, 2.82, .907

Stanley Cup Playoffs: 49g, 31-18, 3, 2.45, .916

Comment: Fleury, 25, was the No. 1 pick in the 2003 Entry Draft. He joins Brodeur as the only two starting goalies in the 2010 Stanley Cup Playoffs who have won the Cup. Detroit backup Chris Osgood is the only other Stanley Cup winner in this year's playoffs. Fleury faces the tough task of trying to be the first netminder to successfully defend the Stanley Cup since Tom Barrasso in 1992.

Brent Johnson

2009-2010: 23g, 10-6-1, 0, 2.76, .906

NHL Career: 270g, 121-100-13-13, 13, 2.64, .903

Stanley Cup Playoffs: 12g, 5-6, 3, 1.84, .931

Comment: Johnson, 33, hasn't been in a playoff game since 2002, when he started for the St. Louis Blues and won a round. He had one of the better records as a backup this season.

Ottawa Senators

Brian Elliot

2009-2010: 55g, 29-18-4, 5, 2.57, .909

NHL Career: 87g, 46-26-7, 6, 2.62, .907

Stanley Cup Playoffs: None

Comment: Elliott, 25, was a ninth-round pick in 2003, the second-last pick of the draft, before he led Wisconsin to the 2006 NCAA title. He's making his Stanley Cup Playoff debut in his first full NHL season. He split time between Ottawa and AHL Binghamton last year and was Binghamton's starter the year before. Elliott had a nine-game win streak before the Olympic and won six in a row near season's end. He's 2-0 against Pittsburgh this year.

Pascal Leclaire

2009-2010: 34g, 12-14-2, 0, 3.20, .887

NHL Career: 159g, 57-69-0-14, 10, 2.89, .903

Stanley Cup Playoffs: None

Comment: Leclaire, 27, was Columbus's first-round pick in 2001. He was the starter until he broke his jaw in November, came back in January and went 3-5, then suffered a concussion in February. Ottawa is the only Eastern Conference team whose goalies have no Stanley Cup Playoff experience.

Western Conference

San Jose Sharks

Evgeni Nabokov

2009-2010: 71 44 16 - 10 4194 3 170 2168 2.43 .922

NHL Career: 563 293 178 29 37 32492 50 1294 14757 2.39 .912

Stanley Cup Playoffs: 65 32 31 - - 3930 6 146 1711 2.23 .915

Comment: Nabokov, 34, the 2001 Calder Trophy winner has never missed the playoffs in his nine NHL seasons, a remarkable record and he has a winning career postseason record. His 44 victories were second-highest in the NHL this season. He was sixth in save percentage and 10th in goals-against average. Nabokov is an old veteran with a world of experience. He's one of the most aggressive goalies in challenging shooters and cutting down angles. He had a bad spell that included the Olympics and the six NHL games that followed but he finished 7-1-1.

Thomas Greiss

2009-2010: 16g, 7-4-1, 0, 2.68 .912

NHL Career: 19g, 7-5-2, 0, 2.77 .906

Stanley Cup Playoffs: None

Comment: Germany's goalie in the past two Olympics, Greiss, 24, played three seasons with AHL Worcester before being promoted to San Jose backup this season. He played very sporadically, as evidenced by his three-game winning streak from December to February.

Colorado Avalanche

Craig Anderson

2009-2010: 71g, 38-25-7, 7, 2.63, .917

NHL Career: 180g, 74-68-2-18, 14, 2.77, .913

Stanley Cup Playoffs: None

Comment: Anderson, 28, was brilliant in the first month of the season, laying a foundation that returned the Avalanche to the playoffs after a year's absence and ahead of when most observers thought their rebuilding plan would become productive. A nine-year veteran of weak NHL teams, Anderson makes his Stanley Cup Playoffs debut.

Peter Budaj

2009-2010: 15g, 5-5-2, 1, 2.64, .917

NHL Career: 197g, 86-70-23, 8, 2.74, .903

Stanley Cup Playoffs: 3g, 0-0, 0, 3.33, .908

Comment: Budaj, 27, was Colorado's starter last year. He played very sporadically for the Avalanche this season, but went 2-2-1 during a five-game span in early December when Anderson hurt his neck.

Chicago Blackhawks

Antti Niemi

2009-2010: 39g, 26-7-4, 7, 2.25, .912

NHL Career: 42g, 27-8-5, 7, and 2.32 .910

Stanley Cup Playoffs: None

Comment: Niemi, 26, is a sports-talk radio broadcaster's dream: You can argue both sides whether he's good or bad. Seven shutouts from 26 wins says he's good. His fourth-best goals-against average supports that until you see his .912 save percentage, only 20th in the NHL, that says his team is better than he is. More than a few observers think the Blackhawks have the skaters to win the Stanley Cup, but not the goalies. To Niemi's credit, nothing you say bothers him and he stepped into an opportunity and kept the job. Only three No. 1 goalies in the West have Stanley Cup experience so Niemi's not the only one in this position.

Cristobal Huet

2009-2010: 48g, 26-14-4, 4, 2.50, .895

NHL Career: 272g, 129-90-11-21, 24, 2.46, .913

Stanley Cup Playoffs: 16g, 6-10, 0, 2.73, .917

Comment: Huet, 34, hasn't played since surrendering seven goals to the Blue Jackets on March 25; has played only once since March 14 and hasn't won since March 5 against the Canucks. He won seven-straight in November, then became inconsistent and lost the starting job to Niemi.

Nashville Predators

Pekka Rinne

2009-2010: 58g, 32-16-5, 7, 2.53, .911

NHL Career: 113g, 62-32-9, 14, 2.46, .914

Stanley Cup Playoffs: None

Comment: Rinne, 27, is the only player in the NHL skinnier than Ryan Miller but at 6-foot-5, he fills a lot of net. Rinne went 12-4-1 with a 2.03 GAA, .928 save percentage and four shutouts since the Olympic break. Rinne played three years in the Finnish league and two with AHL Milwaukee before winning the Predators' No. 1 job last year.

Dan Ellis

2009-2010: 31g, 15-13-1, 1, 2.69, .909

NHL Career: 111g, 50-42-8, 10, 2.64, .912

Stanley Cup Playoffs: 6g, 2-4, 0, 2.52, .938

Comment: Ellis, 29, helped put the University of Nebraska-Omaha hockey program on the map earlier in the decade. He went undrafted, but led the NHL in save percentage in 2008. The Predators think Ellis is a good goaltender, but that Rinne will be great. 

Vancouver Canucks

Roberto Luongo

2009-2010: 68g, 40-22-4, 4, 2.57, .913

NHL Career: 612g, 270-254-33-35, 51, 2.57, .918

Stanley Cup Playoffs: 10g, 6-4, 1, 2.52, .914

Comment: Luongo, 31, had long been regarded as the best goalie with nothing to show for it until he won Olympic gold in February. But he hasn't been good for the Canucks since the Olympic break. Luongo had a 3.35 GAA and .892 save percentage in his last 22 games. Things got worse: He had a 3.44 GAA and .889 save percentage in his last six games. A couple of years back, Luongo was Vancouver's team leader and was named honorary captain.

Andrew Raycroft

2009-2010: 21g, 9-5-1, 1, 2.42, .911

NHL Career: 251g, 103-101-10-17, 7, 2.87, .900

Stanley Cup Playoffs: 7g, 3-4, 1, 2.15, .924

Comment: The 2004 Calder Trophy winner hasn't appeared in the Stanley Cup Playoffs since that year. Raycroft, 29, had one of the better backup seasons this year in the NHL. He's always had a lot of drive, a good work ethic and faith in himself but hasn't been able to hold on to a starter's job, although all his opportunities were with declining teams. If he had to fill in for Luongo, and did a good job, it would surprise a lot of people, but not others.

Los Angeles Kings

Jonathan Quick

2009-2010: 72g, 39-24-7, 4, 2.54, .907

NHL Career: 119g, 61-44-9, 8, 2.54, .908

Stanley Cup Playoffs: None

Comment: Quick, 24, enters the playoffs off a 2-5-4 run, not pretty. Including the two games he started and didn't get a decision, Quick was winless in his last eight starts. Here's the worst part: The Kings wanted Quick to get a win before the season ended, but when they decided they needed a win Sunday against Colorado, they started Ersberg, and won.

Erik Ersberg

2009-2010: 11g, 4-3-2, 0, 2.40, .906

NHL Career: 53g, 18-19-10, 2, 2.55, .910

Stanley Cup Playoffs: None

Comment: Ersberg, 28, was a career minor-league goalie in Sweden until his last two seasons there. He had a losing AHL record and is one game under .500 in the NHL. When the Kings needed to win a game during Quick's tailspin, they brought up Jonathan Bernier from the minors for three wins. Ersberg won his last two starts, closing out the season with a win against Colorado.

Jonathan Bernier

2009-2010: 3g, 3-0-0, 1, 1.30, .957

NHL Career: 7g, 4-3-0, 1, 2.84, .906

Stanley Cup Playoffs: None

Comment: Bernier, 21, was the Kings' first pick in the 2006 Entry Draft. He was recently voted the best AHL goalie this past season. Many people see him as the Kings' goalie of the future. If things don't go right for Quick, the future may be now.

Detroit Red Wings

Jimmy Howard

2009-2010: 63g, 37-15-10, 3, 2.26, .924

NHL Career: 72g, 38-20-10, 3, 2.32, .922

Stanley Cup Playoffs: 1g, 0-1, 3.00, .914

Comment: Howard, 26, was Detroit's second-round pick in 2003. While many people believe the minor leagues are a better training ground, Howard honed his skills first in Hockey East, where surrendering more than two goals in a game calls for an entire organizational review and a bag skate. Howard came up through the American development program, played three years at Maine and four years with AHL Grand Rapids before becoming the Red Wings starter this year.

Chris Osgood

2009-2010: 23g, 7-9-4, 1, 3.02, .888

NHL Career: 733g, 396-213-66-27, 50, 2.49, .905

Stanley Cup Playoffs: 129g, 74-49, 15, 2.09, .919

Comment: We've all watched Osgood, 37, the Red Wings' Stanley Cup-winning goalie in 1998 and 2008, long enough to know coach Mike Babcock has him right where he wants him: Feeling overlooked, discarded and angry. Nothing beats an Osgood, "I told you I could do it but you didn't believe me" press conference after a Stanley Cup victory. Of all the backups in the playoffs this year, Osgood is the most likely to come in and rescue his team, if the need arises to replace a goalie who has never played in the playoffs. Osgood leads all playoff goalies in total NHL games played, regular-season and playoffs.

Phoenix Coyotes

Ilya Bryzgalov

2009-2010: 69g, 42-20-6, 8, 2.29, .920

NHL Career:  258g, 120-96-25, 16, 2.55, .914

Stanley Cup Playoffs: 16g, 9-5, 3, 1.68, .937

Comment: This is the resume of a man who won't quit or be overwhelmed by his surroundings. Bryzgalov, 29, started in the fourth level of the Russian minors and worked his way up to the big league. Then he played 199 AHL games. He has 258 NHL games under his belt and was the backup goalie on the 2007 Anaheim Ducks Stanley Cup champions, who made him their second-round pick in 2000. He's big, smart and strong and won't be fazed.

Jason LaBarbera

2009-2010: 17g, 8-5-1, 0, 2.13, .928

NHL Career: 124g, 45-49-11, 4, 2.85, .906

Stanley Cup Playoffs: None

Comment: The two-time AHL goalie of the year, LaBarbera was the Kings' starting goalie in 2007-08. That was a tough team to shine on and LaBarbera has moved on. He's a big goalie but inconsistent at this level. But he was a smart free-agent signing to back up Bryzgalov and the tandem has worked well.
