Would much rather have Aldridge than Griffin. Griffin is a poor defender and shot blocker, and his game relies heavily on a very suspect jumpshot and an underdeveloped post game (if you can even call it that; at this point he basically just dribbles between his legs a bunch of times and then jumps into his man while flinging a shot at the basket). He's not nearly as efficient as Bosh, Aldridge, or Love as a pick n' pop forward, and he needs too many bounces of the ball and, as a consequence, time and space in the post before he gets any kind of shot up.
He's obviously exciting as fuck and one of the rising stars in this league, but I really don't think he's a good fit at all for an international style of play with the kind of perimeter scorers the USA team will have access to. The US squad will have plenty of "ball dominators" with LBJ, Kobe, CP3, Durant, Wade, etc. Griffin's clogging post game and ineffective jumpshot really doesn't improve the roster much at all, IMHO.
