Yeah, Jenkins situation is weird. I don't have an insider, but I'm pretty sure that a long-term Jenkins contract isn't going to happen, probably no matter how good he plays over the next 2 years. But they are in the position where he is one of their best 5, because he is so talented. Just apparently doesn't have the personality they want or something.
I think they would jump at the chance to trade/upgrade him, but the problem with that is: A) he's young, good and on a cheap rookie deal and B) they haven't put forth the effort to spend for someone better and C) they won't get any value by trading him
