Firstly, it was reported that Burke was one of the few who actually put Ryan on his final roster. Secondly, what is Ryan going to offer that other forwards can't? He's got a good shot, great hands but is very slow and is known to look lethargic. He had an awful 2012-2013 and is having a pretty mediocre season this year as well, having only 7 points in 17 games following his omission. Also, Oshie wasn't the only forward that showed up - he wasn't even that good against Canada. Up front, Kesler and Callahan were pretty good. Also, I don't think the USA underachieved, they actually played very well overall in the tournament, they just got beat by a better team with a roster that is more stacked.
Weber - Keith
Doughty - Vlasic
Pietrangelo - Bouwmeester
Price
Not many teams are going to score on that defense.
