Zeller is a Trex rebounder. He doesn't have a nose for the ball. Poor passer his court vision is avg for a 7 footer at best. You would get frustrated with him quickly. Don't see how he fits what Brad wants to do.
Throughout his career, Charlotte was always rebounding well with him on the floor.
Even if his counting rebounds weren't impressive team-wise he gets the job done.
That's more important to me than his RPG.
Brad always liked centers that can run.
Maybe you are right saying he would be underwhelming, but I wouldn't expect an allstar, just an upgrade over Kanter.
IMO he could be that.
Theis is too small to help us in either Philly or Milwaukee series.
Zeller is 7 footer like Kanter, but a better defender.
