If they want to bring him in as a non-roster assistant coach, that's ok I suppose. He could suit up if there are a huge spate of injuries (on a 10-day contract), like Dana Barros did a few years ago. But he would be a total waste of a roster spot.
This sums it up nicely, and is exactly what I said way back at the begining of this. It sounds so simple and is unless Sam starts whinning about wanting to play.
