I think John Henson is the biggest stiff in the entire draft. Mechanical player.
Reminds me of Keon Clark.
I am certainly not the expert and you might be right, but I am curious why you think this. As I watch the video on Henson he seems very long and has good mobility around the basket. He is a great catch and dunk or layup type player. He is a world class shot blocker and does not do it from the weak side. He mans up and just blocks shots, many of which he recovers after the block. He is a very good rebounder.
We've just never had a mistake eraser like that.
