I've seen Sean on many many nights where he's bright and cheerful and others where he's not as much. Sean will always have his weight issues but especially when he can't train effectively.
Sean May has been battling knee problems for what must be 3 seasons now and still has a long road to recovery. I'm sure there's a lot going on in his head. Microfracture surgery is very serious stuff for a career basketball player.
Saying that I understand your concern O'Hara; because I guess the word on the street is that he has lifestyle discipline issues. I don't know much about that.
What I've seen though hasn't given me any worries at all beyond his normal ability to recover from his surgery.
If Sean May can return to his potential; he can be a great NBA player and Bobcat's asset. At this time though, who knows? It'll be interesting to watch; and as a Bobcats fan; he's got my full support for sure. I hope the Bobcats are feeling the same way.
