I'd feel better about Tinsley than about Marbury, but that'd [dang]ing with the faintest praise possible. Tinsley, when healhy, has been a pretty good player but he's a nutcase. He *might* be able to fit into the C's with their veteran leadership, but don't he and Pierce have some, uh... rather negative history between them?
I don't think we're in a position to judge. If Tinsley is serious about wanting to play, and is willing to make the sacrifies to come in for 15 minutes a game, run the offense, play D, not be an ****, he could help out a LOT. But, there's no way for us to judge where his head is at right now. Is he willing to take a step back? If he were to come in, play hard, play well, be a good teammate, he's young enough and talented enough where he could parlay that into a good situation for himself down the road.
But, we don't know where he's at mentally.
