The trade deadline passed at 3 p.m. Monday, as several teams tweaked their rosters with hopes of enjoying a nice run during the Stanley Cup Playoffs.

When the smoke cleared, there were only four teams in action Monday night, but both games certainly had huge playoff implications in the Western Conference.

Here's a look at how the races in each conference shape up after Monday night's games:
