I think he would make a great backup 2/3 for us.
He won't shoot very effective, but with the second unit, it's hard to find a wing player who would.
He is at least capable of making some very, very difficult shots, and he can still get on a hot streak and score in bunches.
If he can do that AND defend, rebound, and make the extra pass like he always could, he would be a fantastic pickup.
