This is the definition of low risk high reward. There is really nothing to lose. He plays well then we get a good rim protecting high flying center... He plays bad he sits and he is gone.
If things work out I would our bench line up make even more noise. Thomas, Smart, Crowder, Jerebko, McGee has potential to be one heck of a jump start, run and gun second unit.
However, a line up consisting of Bradley, Turner, and McGee is going to be painful to watch from an IQ perspective.
