Let's not be too harsh. The US was the only team in the tournament not to lose a game in regulation. Still, they finished fourth, due to the two 3-on-3 overtime losses in the two medal games.
They were also the only team to win all 7 games in the group stage (6 of them in regulation). They were the Boston Bruins of this year's Worlds.
And yes, TJ Tynan got a couple of votes for the tournament's All Star team, indicating he impressed more than the Sabres star Alex Tuch. Eventually, another AHLer got into the All Star team: Rocco Grimaldi for 14 points (7+7) in 10 games.
