Big time skating guy with PK ability points to Erik Johnson or John Carlson for me. If you want a PP threat that is right handed, might as well go with two-way Justin Faulk who has gotten glowing reviews from Team USA. They will bring eight.
Suter - Shattenkirk
McDonagh - Bogosian
JMFJ - Faulk
Martin - Carlson
Probably the eight I would bring, Erik Johnson wouldn't be bad either. Olympic vet, big rangy PK type, but at this point I expect big things out of Faulk and the more I think about it I don't like the idea of leaving him home. Maybe you have Carlson and Bogo compete for one spot, want the McDonagh pair to be a shut down deal. Faulk will have to prove a big PK guy to make this lineup happen. Carlson is a great PK guy, I think that helps him, he is also good two way D-man, but can be counted on for defense and would fit well with McD. That second pairing is going to be a big shutdown group that is physical, so both Bogosian and Carlson make a world of sense and they skate well for the international surface.
This defense should be young, that is where our talent is on the backend, exciting thought in terms of the next decade of international hockey, we look to be loaded with rearguards for a while and it's an exciting group.
You can bring Big Buff as an offensive weapon, but Faulk has a ton of offensive ability and a semblance of D. D and goalie have a lot of tough choices, really the good news is this teams selection is finally getting quite hard across the board, some talented players are going to be sitting at home, that is a good sign for USA hockey.
