I think Rondo and Coach Stevens are going to make Zeller significantly better than you think.
Zeller has great hands, a good iq, and great mobility for a center. Rondo is going to get Zeller lots of easy looks, like he did with KG.
And Stevens and Zeller are both from Indiana, and I believe Stevens recruited him out of high school. Stevens is creative enough to help Zeller succeed to his potential.
I think he'll be our starting center from day one, and I think we'll start out the season with a winning record, like last season.
