It seems to me that players change where they play a lot and the lineups are never set. You'd think it would be 14-15 guys total that play, but it seems there's someone new every time a match comes up. How do you get continuity and familiarity with your teammates if it's someone different every time?

Clearly, Berhalter had a TERRIBLE lineup to start. Finally brings some guys in the 2nd half who should've been playing the whole game, and voila! Steamroll them in the 2H (like they should have all game). I'm not an in-depth soccerhead, so I may be missing that other countries move their lineups around a ton, but it's just weird to me.
