Las Vegas sports books favor the New York Giants over the 11 other teams in the NFL playoffs to win the Super Bowl, giving 2-to-1 odds on the NFC's No. 1 seed to repeat as champions.

The Tennessee Titans are the favorite among AFC teams to win a title at 4-1, closely followed by the Pittsburgh Steelers at 9-2.

The Giants have the easiest road to the Feb. 1 Super Bowl, while the AFC teams are more evenly matched, oddsmaker Mike Seba of Las Vegas Sports Consultants said Monday.

"You want to be in the NFC," he said. "The AFC is closer bunched — there's not a lot of difference between your top seed and the six seed."

The Giants have a first-round bye, then would have to beat either the Arizona Cardinals or the Atlanta Falcons to reach the NFC championship game. Sports books set 40-1 odds on the Cardinals winning the Super Bowl, and 15-1 on the Falcons.

"You just have a bigger difference there in the NFC — that's why the Giants are favored," Seba said.

Sports books gave 30-1 odds on the Titans before the season began, longer odds than the Steelers, San Diego Chargers and Indianapolis Colts. But Tennessee started the season with 10 straight wins while the Colts started slowly and San Diego lost eight of its first 12 games.

Jay Kornegay, executive director of the race and sports book at the Las Vegas Hilton, said there is essentially no difference between the Titans and Steelers, though the Hilton has the Titans slightly behind the Steelers because of Pittsburgh's popularity among bettors.

"The way we see it, it's a crap shoot," he said. "It's going to make for an interesting playoff. I wouldn't be surprised if we don't see either of the one or two seeds from both conferences in the Super Bowl."

The No. 3 Miami Dolphins were the AFC's biggest surprise during the regular season, but are still the conference longshots to win a title at 30-1, according to Las Vegas Sports Consultants, which recommends betting lines for 90 percent of sports books in Nevada.

Oddsmakers give Baltimore, the lowest seed in the AFC, a 14-1 shot at winning the title after opening the year at 125-1.

"Baltimore and Indianapolis can get there almost as easy as Tennessee," Seba said. "They have to do it on the road, but as we saw last year with the Giants, it can be done."

Each of four road teams — Indianapolis, Baltimore, Atlanta and Philadelphia — is favored in opening-round matchups to be played this weekend. The top two seeds in each conference earned first-round byes.

Kornegay said his oddsmakers are eyeing Philadelphia as a bottom seed team with enough momentum and confidence to make a run in the playoffs.

"When everything looked like they were not going to make it, somehow everything fell into place," Kornegay said. "They could be the Giants of this year."

The wild card Giants beat the New England Patriots in the Super Bowl earlier this year after starting the playoffs as the fifth seed in the NFC and defeating Tampa Bay, Dallas and Green Bay.
