I think he actually has been passing more, and looking for his own scoring less, to the point where he has become a nice role player. He still needs to be on his game to stay on the floor though. There's no point in keeping him out there if he's ineffective at doing what he's best at.
Toughness and rebounding will also improve once TJ is back in the fold. As long as the defense is not scrambling to counter guards blowing by their defenders effortlessly, the rebounding will not be a major concern. Note that did not happen all that much last night, and when it did, the Knicks scored without needing a rebound. And if Bargnani
does not add to that mix, then there are real concerns as to the direction the team is going in. I still think he'll answer the call, but maybe not so much this season.
