AV is probably a dirty type player, Sasha a bit too. To me, the dirty types are the guys on the opposing teams you hate, usually foreign players, because they give that extra contact and bump people around while getting away with it. Guys like Nocioni, Tony Parker, Bruce Bowen all bug me like this. I guess AV is the Cavs version.
As for AV starting, he would really need a jump shot before I'd be comfortable with that. Gooden gives us a guy who can score, and its nice having that option out there. There have been many games where Gooden is the only guy who can get things going and he keeps us in the game. I would say his rotations and stuff are as good as AV, just AV has wilder hair so people tend to notice him more. Also, AV tends to give up lots of stupid fouls, this needs to be controlled a bit too if hes going to start, not much of an issue if hes just off the bench.
