Brendan Haywood is a good backup big man, but he's out for a couple of months with a foot injury. That means the Bobcats need Bismack Biyombo to give them quality minutes behind Jefferson. He is an energetic, athletic player who can rebound and block shots, but his offense hasn't developed much in two seasons. He has a lot of trouble finishing around the basket, and he has to get better at screening and rolling. He was drafted too high [No. 7 in 2011] for what he is.
