I'm with EJ. It's a given that Tony was a very good defender and great athlete, and he has flashed an ability to get the ball in the basket. However, he's been extremely inconsistent and injury-prone, and his basketball IQ, ballhandling ability, shooting and passing were all always subpar and nothing indicated that would ever change. The amount of times he slashed to the basket and finished is roughly equal to the amount of times he slashed to the basket and turned the ball over, through a charge, bad pass, strip or just flat out losing the handle (or dribbling off his foot).
Tony was fun, but he probably will never be more than an 8th or 9th man on a good team. I wouldn't mind keeping him around and I'd rather get something for him than have him walk away, but there's no way I'd give him $2.75 mil a year to stay and find out if he'll get his athleticism back because like I said, even if he does, there's still plenty of problems. As much as he could be a much better player, he's not, and maybe we have to look to younger, cheaper alternatives (Giddens, Walker) to fill his role. If Tony would take a one year, $1.5 mil deal, I'd give it to him, but not a $2.75 mil deal.
