Why do people think Black is some kind of jumping jack? He seems at best average to me. He's more Charles Oakley than Jason Richardson.
He does a pretty good job rebounding at 6'7 when most B1G post players are 6'9 and up. I think when he gets his feet set he's pretty explosive, and he has long arms for his height so he can grab the ball higher than maybe a normal 6'7 guy can.
