This is no surprise, he was injured for most of the off-season, and I'm sure he is too stressed to eat properly or train. This is what he gets for being an idiot and cheating on his wife. It's going to get a lot worse for Kobe.
Shaq should just get all stressed out so he can lose ANOTHER 15 lbs. Just kidding... But I don't think Kobe looks too bad, although he looks more like his rookie form; give him some time, and he will be back to full strength.
