Possibly because Orlando is too familiar with Gooden's flaws? (Though I do believe he still has a home there.) He's a notoriously bad decision maker on both ends of the court.
On the other hand, he can score in the paint and has a nice mid-range game, is good on the glass, plays physical defense, and I remember he gave Garnett fits in their first match up last season, before being dealt to Chicago.
Still that ducktail on the back of his neck was maybe the worst look I've ever seen on the court. (Second runner up, Skinner's dyed goatee?)
