I don't think playing under a Brown disciple in SA is an indication of how Jackson will mesh in Charlotte. If anything, I think Steve did well in SA because he was a young guy who was mentored and kept in check by some very stable, seasoned veterans on that SA squad. He didn't really develop in to the delusional, petulant, punk until he left the stable structure of SA. I'm not sure he's going to get the same peer support from the likes of Boris Diaw, Tyson Chandler and Gerald Wallace.
This guy is well on his way to grabbing the baton from AI to be the new and improved poster boy for the spoiled, delusional athlete. In a preseason game against the Lakers he was spouting off about how he hated Kobe (no big deal, get in line with the rest of the majority of the U.S.). What's significant is he continued to spew rhetoric about being as good as Kobe is ... ummmmm ... ok ... SJax ... put the crack pipe down, donkey.
I think he might behave for a while in Charlotte since he was essentially granted his wish of getting out of Golden State, but I don't see it lasting long under Brown.
