I think they should give Bradley time handling the ball and running the offense. He will play primarily off the ball on offense but he is still really improving and I believe that he can develop into Dennis Johnson or Chauncy Billups type of PG or combo guard. It may still be 2 years from now (when he will be what, 25) but I think Bradley still has a ton of ceiling.
I do not think they should play him to be focused on PG this season but I could see it in the future. I know, the "Bradley sucks as a PG" replies are coming but his rookie year, he sucked as a player and look how far he has come from there.
