He's still shell shocked from the BIG hit he took last year....
Maybe but I think it goes deeper than that.
The guy is the consumate egotistical athlete focused on himself and grandstanding in order to get attention focused on him. It goes all the way back to high school when there are clips of him show-boating during games back then.
How many times does his ego and immaturity need to surface before people stop giving him a pass and realize that he's simply not worth the aggravation that he brings with his game? You combine that with the rumors about his off-field conduct and that he's been "lucky" to avoid being caught in the wrong place at the wrong time and I question the wisdon of any team that gives him a big guaranteed contract.
