Great question. Now that Sheed and TA are gone, I'm not sure what I'll be griping about this year. I'm sure there'll be somthing... I suppose I can count on Doc's rotations really driving me nuts, but I can't very well call Doc my least favorite, since he's proven himself to be one of the best in the business...
So...I've never liked Jermaine O'Neal. I think as his skills have declined, he's become more of a bully/thug, even more than he was. Remember the roundhouse punch in the open court of a fan that was (very, very stupidly) running onto the court after him? If his back foot hadn't slipped, I swear he could have killed that idiot. Worse is that he seems to like being a thug on the court. Perhaps I'll still cheer for him as a Celtic, but it won't be because I like him at all.
Shaq may prove to be a bigger distraction than he's worth as a player at this point, but he's a hard guy not to like.
I'd say contenders for least favorite will be Von Wafer, Quisy, and BBD in that order. BBD has to figure out how to get the ball up from down low or stop trying to be the post player he clearly is not.
