You prolly don't even need another big to get any real minutes except for a few garbage time minutes here and there after ADavis to be honest. Erv looks kinda foul prone so you'll need Davis just in case he has one of those Chris Dudley games. Give your best players heavy minutes. And I would go fortson over Williams if you felt the need, while he's not the most skilled, his athleticism + rebounding would make him an easy 10/10 guy if he had the PT. You should be good with just AD, Pike, and Martin as your reserves and run with an 8 man rotation
