Probably never. If he hit three shots tonight, perhaps this thread isn't started. I don't like Marbury personally but I can see he's trying his ass off, he's putting more effort into playing defense than he has since he and Spree were playing with KG, his shot is all over the place which is a sign of not having his legs under him, and his ability to drive the lane is still obviously there and invaluable.
I say give him 10 more games and all the Starbury is washed up and sucks talk will be gone. Of course by then we could see mister attitude coming out, so who knows just what he'll give this team this year.
