I can think of two reason the Flyers were able to take out the Canadiens so easily.
1-Martin Biron > Carey Price.
2-The way Montreal fans rioted over their first-round win over Boston. Come on, people, these are the motherloving Canadiens. Celebrating a first-round win like that (complete with setting vehicles on fire) is like Yankees fans storming the field after taking two of three from Kansas City. OK, maybe Baltimore, but still.
The lesson is very clear. If you act like you've won it all too soon, Fate will tell you that you've won as much as you're going to.
Au revoir, les Habitants.
