If you read this article it pretty much details all the crap JR Smith brings to the table, but it also mentions his upside. It's "upside" that gets players who have run out of chances, another chance.
Welcome, JR Smith.
I'm trying to think of a scenario where loud, brash, obnoxious, irresponsible, selfish and moronic team player joined a franchise, changed stripes, and helped a team be successful. It's not easy coming up with one. Usually, the result is the same.
Terrell Owens does come to mind, his days with the Eagles, where he almost singlehandedly won them a Superbowl. The post-TO fallout, in my opinion, was ownership's fault, and not his. But it didn't workout in the end.
Usually when you sign the "Pacman" Joneses, the Milton Bradleys, the Carl Everetts, and the Derrick Colemans of the world, it fails.
BUT...here's hoping that a YOUNG player like JR Smith, back in the NY/NJ area, can get lost in the shuffle, remain quiet, come off the bench, and help them win some games.
I can't even venture a guess of how this will go down.
