This is optimistic. I don't know that a guy like Diop ever comes over, and if Travers doesn't develop a shot, he's going to wash out in the pros. Merrill is 27 already and is extremely limited defensively. Mobley is unlikely to be an offensive focal point in any NBA unit outside of garbage time and he's currently bellow average in the other aspects of the game he'd have to be at least average in to stick on another NBA roster.
Even guys like Bates and Porter, who I could see becoming second unit guys one day, need to put in work against better competition than what we're seeing right now before I'd feel comfortable with that prediction.
