He's pretty good as far as bench bigs go but I'm with Lefty. Lebron finding his post-AS break stride, Wade getting healthy, and them combining to activate the everloving out of their Wonder Twin powers has something to do with this.
Can't really laugh too hard at the teams that didn't want to touch him. Realistically he's probably just a headcase and potential problem in any locker room where things aren't going as smoothly as they are in Miami (which is looking like a near lock for a repeat). Pretty short list of teams even close to that same class of success right now. Clippers? LOL at the thought of Vinny keeping a leash on him. Thunder? Birdman to OKC isn't just a bad idea, it's a pitch for a Breaking Bad spinoff.
It's a coin toss for what the Spurs could have done with this guy. Could have been a decent reclamation project, could have been a short trip to homicide charges for either him or Pop.
