I know I'm not a GM or coach, but someone please explain why they resigned Zeller?
He projects as a third tier center behind Horford and Olynyk - given the injury history of both guys we kinda needed that, and as a third tier big he is fine.
You guys have to realize that in 14/15 when Zeller was given a consistent role, he played really well - had his limitations sure, but he was more then good enough for a backup center role. Last year (with the frontcourt logjam) Zeller got buried on the bench and never really got a consistent role in the rotation. I don't think it's a surprise that he's a little rusty.
Same is true of these young bench guys. Rozier has barely played outside of summer league and the D-League. He was solid in the playoffs last year and he has reportedly impressed in scrimmages, so I've got no doubt his play will improve as he grows comfortable and gains experience.
This is the preseason - if there's any time for these guys to dust off the cobwebs, it's now. Let them play, they will be fine.
