Who said the OL was sucking in 2015? Who said play-calling doesn't impact OL play either?
What's your point?
I'm not talking about Jerry and in fact I said, it was probably because of influence from Callahan and shift when in that direction. Just like Jerry squashed the Sharif pick based on his coach Marinelli, it's clear he had the ear of Callahan as far as OL is concerned.
Callahan worked Fred out. Callahan coached at Wisconsin prior and Callahan watched Wisconsin. So basically, Callahan wanted Frederick and thought he'd be a perfect fit.

"We're talking about a smart player, here -- he is, after all, about to earn an engineering degree after just three years. Cowboys offensive coordinator and line coach Bill Callahan told me that, when he went to work Frederick out before the draft, he put 23 protections up on a board for him to learn, just in case Dallas ended up taking him. Last week, Callahan asked Frederick to draw the 23 protections -- and he was perfect."
As far as the Commanders, Gruden was there last year 'calling plays'. The OL was horrible in pass protection and Cousins was playing. And the passing game was run by McVay this year. Gruden essentially was running a coach by committee philosophy.
So we need a better coach and play-caller.. You won't find me arguing against that point.
