When you look at NYI/WPG/STB/Vegas/(Washington?), and the success they are all having with big gritty players should a team focus on that? Is Size + Grit >>> Speed + Skill
In my estimation, it is neither skill, nor grit, that carries teams --- it is effort, and dealing with adversity. Tampa looked flat after Game 1, and that is because they had not faced that level of adversity all year.
Pittsburgh was much the same; they relied too heavily on the strength of three or four players, and when they couldn't make it happen, the team fell flat. Look to Colorado to see what happens when your superstars show up and do superstar things.
Calgary? Colorado is just outplaying them. It's not a grit and size vs speed and skill thing; its just key players showing up at key times carrying their team through a team who's key players aren't doing it.
Toronto does not have the defensive group to carry them through Boston consistently. Despite Rask playing like complete garbage half the time, the Leafs can't find a way to win because they are porous and give up far too many opportunities. Boston plays a physical style of hockey, but they are still incredibly fast and have some incredibly skillful players. That series will come down to refs; if Boston can play the physical game, they will win because that's the way their team plays. If it boils down to clean 5on5 hockey, I don't like their odds when Andersen outplays Rask.
I think the faster, more skilled Dallas is giving Nashville a run. I also feel that the Blues are faster, and more skilled. Both of those teams suffer from poor defense and poor depth, however.
