I agree with a lot of your picks. Especially some of the unsung heroes like Pyatt and Letestu.

Colorado Avalanche - I'd go with Barrie. Doesn't get the same recognition as other defensemen with his level of production.
Montreal Canadiens - Phillip Danault - I actually think he's overrated because he was used too high in the lineup.

Wow, everyone's saying Hjalmarsson's underrated, so i don't think he is.
