key personnel changes vs 2018 on offense:
JR Sweezy at Guard
Justin Murray at Tackle
AQ Shipley at Center
Kyler Murray at QB
Those don't strike me, by themselves, to be the kinds of personnel changes that would turn a historically bad offense into an average NFL offense --
I have no doubt the offensive coaching was a lot better than it was, but even in that personnel grouping you're counting out Kenyan Drake, Damiere Byrd, Pharoah Cooper... all guys who played significant time.
Given that this is a thread reviewing K2, to switch it back to that topic, I agree he's got some good offensive philosophies and changed them through the year, but I doubt his decision making in real games and dislike what I and others feel is a nearly complete silo from anything defensively.
That's why I gave him a D. After the Seattle game, I'm now a little more hopeful that he can improve upon that with another year, but his personnel still isn't going to be wildly upgraded. We'll have to see.
