Right now we have 3 centers. And 18 players total on the books. DA has to move some pieces before he can start signing more players.
I think Zeller will be good. He's healthy and isn't behind two other centers. His last handful of game he was really good. While not a true rim protector, he has a lot of other really good skills. Plus Stevens recruited him when he was in highschool, both being from Indiana, and most likely played against him in college. So he would know how to use him best and what he's capable of.
