Could the way they let the Center market play out be a subtle vote of confidence for the rookie? The sounded pretty impressed with his athleticism via the private workout he had. I believe "Saw him do some pretty impressive things that a guy his size shouldn't be able to do" is close to the words used. I think late in the season he looked like a guy who could win off the dribble, more so than he showed at any point. That could be a part of his game that's an unknown because it wasn't showcased in college.
Likely still need a stretch though right...just not a rim protector.
