They're all excellent captains. Real 'heart-and-soul' type players.
I'm Canadian, but I have to say I think Team USA has a great chance at winning gold in Sochi (if the NHL allows its players to participate).
Most of my favorite players right now are American; Callahan, Parise, Backes, Kessel, Kesler (except for his damn diving nonsense), JJohnson, Suter -- and then you've got the slew of excellent American goaltenders (Quick, Thomas, Miller, Howard, etc.)
I think it will also be good for the marketability of hockey in the US if there are more homegrown players on the teams -- especially when they're core players and captains.
