We have toughness at all the other spots except center. We've discussed Hawes and May here but we do have another big that has toughness to spare: John Brockman. I don't understand why we aren't playing him more in the middle. Sure he's only 6'7" but he's a big body that can clog up the lane and he isn't afraid to bang.
6'7" is not 'another big.' Brockman has talent and toughness and he's great off the bench but he is not the answer to our starting center question.
