This really shouldn't come as a surprise. If there's one area he's been consistent in throughout the duration of his career it's his bad attitude and poor shot selection. We all know Jack can shoot - and when he's on, he's on. But Stephen takes the "if you're cold just keep shooting" strategy to the extreme. Someone already mentioned it but I hate the fact that he constantly complains to the refs instead of getting back on defense. You don't see that kind of garbage from someone like Blake Griffin (who actually deserves more calls in my opinion).
Its easy to say, "Let's just trade him now," but you will be hard pressed to find a team that wants to take a risk on him without having to take back some garbage for your own roster. Look at Indiana for example - in order to get rid of Harrington and Jackson, they had to take on the atrocious monster contracts of Dunleavy and Murphy, a move that handicapped the franchise for at least 3 years. In fact, Dunleavy will come off the books this summer (we were lucky to get Collison for Murphy, but we had to take Posey's horrible contract in return...you see the chain reaction starting to take place now).
And as much as you dislike Jack, what kind of a scoring option will you have without him? I seriously doubt Wallace will pick up the slack. Kwame can't be relied on to continue his current pace. DJ is inconsistent. Henderson is still developing. You won't get anything back that will replace his scoring (and I am NOT defending the guy...I can't stand him and I find it ironic that I wound up following another one of his teams now).
