The guy can't guard the same position on the other team. So you're right, he can play within a certain system. You have to make sure you have a PG who can guard a 2 so he can guard the other teams PG. Good thing that's convenient.
You can't compare #s against other PGs or SGs he played against, b/c he played against whoever wasn't as opposing defensively. And when the bulls needed a stop? You can bet your happy ass BG wasn't in the game. always Hinrich...every single time..
But, hey, you don't want to agree to disagree...fine..you win.
