Notice Chaney went way more spread and pass when he got here and has previously too, as well. He's very flexible to his HC and team. Even then, he had them #4 SP+ (tempo adjusted) offense last year and 38 PPG. Now 31 PPG in Fromm's junior year lol. Coley is beyond bad.
But I think the 70s offensive mentality is a Kirby thing, just like it was with Les. No matter the OC, the promise of change, the great QBs, he repeated the same offensive style. Great vs less talented teams, but not good enough vs talented high powered offenses. Same as Kirby has seen. Hopefully he keeps bein himself lol
