Forbes bulked up, and Spoon is still stronger than him. He can handle contact without coughing the ball up. Forbes is a target on both ends of the floor, because any time he puts the ball on the floor more than once, the defense is coming after him - and he's either got to dump it off to someone, or it's a turnover.
I don't know if Spoon is ready to deliver 3-pointers against NBA defenders, but I would take him in every other facet of the game right now. And he's going to get better - Forbes is done improving. This is it for him.
