It's not about the number of touches. Mobley got the ball plenty this season in static situations where he couldn't do anything with it. He's not that player yet. Clanking even more long 2's with a second in the shot clock wouldn't have helped his case one bit.
The way to make Mobley look good is to pass him the ball at the FT line, with people cutting, screening and moving around him. That's when he's a true triple threat. But that's an offensive strategy that needs to be put in place by the head coach.
