I see John Grahame starting for the US against Slovakia, but I think that he and DiPietro are pretty much at the same level right now anyway (
though I do like DiPietro's potential to steal a game singlehandedly.)
If the US can get out to an early lead and control the puck well then they can neutralize Slovakia's speed. The American team is composed of some very hard working sparkplug type players like Gionta and Blake who can keep the pace of play up, but ultimately if the Slovaks take an early lead I don't see the US being able to fight back.
Go America!
