I filled out a bracket on NHL.com, which has a fun and easy tool to use. Here's a screenshot of it:
As you can see, I have the Bruins winning it all (big surprise.) I do have a few interesting upsets, though, and the first round will be fascinating to watch.
WESTERN CONFERENCE
Avalanche vs Wild
What a story for Colorado this season, going from a basement dweller to the top team in the West. On the other hand, Minnesota is a team that just squeaked by. This is an easy one. Avalanche in 5.
Blues vs Blackhawks
Wow. The Blues were a top 3 team all season long, but a major collapse in the final 6 games (and .500 hockey since the Olympics) have brought to light some major issues. They're dealing with some major injuries (as are the Blackhawks) but I'm going to go with the proven entity here. Blackhawks in 7.
