Canada: Solid team. Some great players: Crosby, Stamkos (although he's obviously a question mark after the serious injury), Toews, Bergeron. Solid defense. Topnotch management with Stevie Y. and topnotch coaching with Mike Babcock. Goaltending is the big question mark.
USA: Decent team, but not a favorite to win.
Sweden: Super-stacked team with 6 Red Wings, plus Backstrom and Karlsson, no obvious weaknesses, great leadership in Zetterberg and Alfie.
Russia: 4 forwards who are as good as or better than the top 4 forwards on any other team: Datsyuk, Ovi, Malkin, Kovalchuk. The rest of the team is not close to that level.
Prediction: Gold Sweden, Silver Canada, Bronze Russia - but I won't be shocked to be wrong on any of those.
