I was thinking about this yesterday.
Anyone know of a OL-man turned HC that didn’t want a meathead offense? As a player you’ve been trained to beat and maul the man in front of you. Which makes sense. You can’t win football without controlling the LOS, either on offense or defense. Even in today’s CFB. Bama, UGA, Clemson, and OSU all have (or had) excellent OLs and/or DLs.
The difference is those HCs - Saban, Meyer, Day, Dabo, and Kirby weren‘t former OL. They understand the key to football is still the LOS. But, as skill players (DBs are skill players IMO) they also understand Xs/Os.
Maybe I‘m posting out my ****...it’s Sunday…
EDIT: Andy Reid is a former OL/OL coach. But later became a QB coach. He also started his career as a GA at BYU.
