how well do you think Keyon Dooling will impact a player like Royce White...
While he couldn't hurt, I don't think that is the problem. This is a legal issue, not a basketball issue. I think it is going to take the Rockets taking the whole thing a bit more seriously, before it can even get to the point where White can try to redeem himself.
Here is my theory of what is going on right now. I wouldn't be surprised if one of the biggest issues here comes from Sampson taking over. I bet management and HR had sat down with McHale and layed out exactly whats going on, and what he needs to do, before the season. But I wouldn't be surprised if Sampson didn't get that talk (at least not yet). So, when he took over, he started coaching the only way he knows how, and not putting forth the obligatory effort to make accomodations for White.
