I don't think you can underestimate how huge a strong team USA would have been for this tournament. Toronto was packed with USA hockey fans during the round robin. Alot of people are saying the Tourny lost gas when team NA was eliminated, but I really think handcuffing the US was the biggest problem. You have 4 hockey super powers really - Canada, US, Russia, Sweden - Finland and the Czechs are in the next tier and then 2-4 teams in a tier below that. If you handicap any of those top 4 teams other than Canada by not allowing them to bring some of their best players, the tournament suffers.
Would the U.S. have brought some of those young guys? A few for sure, maybe not enough of them to make a difference but who knows. Still the U.S. being awful wrecked this tournament and team NA contributed to that. There was a notable lack of "classics" or big rivalry games in this tournament. I can't pick any 1 game I will look back on and say I'll always remember that one.
