I know everyone wants to root for USA, and seeing strong up and coming talent be a part of the team is inspiring, but don't let that cloud your judgement here.
I wish USA the best, and one day hopefully they can compete with Europe, but it's pretty clear that Europe is still the heavy favorite. Every single player on team Europe is an experienced champion, and could all be contenders for world championships.
Team USA has only one player at that level right now, with a couple players who have potential to get there soon, maybe. As much as I'm rooting for these young guns to do well, the reality is they aren't world class players yet. None of them have done anything on the world stage as of yet, with the exception of Shane and Corey, and Corey hasn't done much in a while. He's past his prime.
Root for them all you want, but don't ignore reality.
