Two things immediately come to mind:
1) People assume that Bobby's out of shape. I think he'll be in great shape. He hurt his wrist, not his leg or anything. I doubt that he's been taking the past 4 months off. His shot might be affected, but other than that, I think we'll see the same ol' sparkplug Bobby Jackson that we've always known.
2) Having him back is a good thing, especially against a team like Seattle that might employ a backcourt duo of Ridnour/Daniels at times. But if I see Mike, Bobby and Cuttino in the game at one time, I might scream.
