Many on BBI say the OL will be better because Zeitler is a major upgrade and that the center will be better by playing next to him.
How do we know that Zeitler won't be worse because of who he is playing next to? In CLE, KZ was playing next to JC Tretter, a top ranked center.
So, was KZ so good because he's good, and Tretter benefitted, or was Tretter so good that he helped KZ?
Probably a bit of both, but if that's the case, will KZ's play go backwards playing next to Pio/Pulley, or will their play be elevated and his continue to be as strong?
