In case you haven't seen it anywhere else, here's the US World Jrs. Roster.
Justin Abdelkader-Michigan State
Nate Gerbe-Boston College
Bill Sweatt-Colorado College
James van Riemsdyk-NTDP U18
Trevor Lewis-Owen Sound(OHL)
Comments: The big news here is that Bobby Ryan indeed did not make the team. Instead they opted for some former NTDP guys like Fraser and Geoffrion. It looks like a nice mix of grit and skill. They'll probably really need Okposo and Mueller to carry them offensively.
Kyle Lawson-Notre Dame
Brian Lee-North Dakota
Taylor Chorney-North Dakota
Comments: Mark Mitera won't be on the team after making it last year. He hasn't had a great year, and I've heard that he's also nursing an injury, which could explain why they want to leave him home. Lawson had the reputation of being a favorite of coach Ron Rolson, which explains his presence. I know very little about Zimmerman.
Comments: Frazee is still on the team despite not having a great year. I think he's better than people give him credit for though. It should be interesting to see who gets the most playing time. My guess is they split time at the beginning, and they try to ride the hot goalie in the medal round.
