I think it would be pretty shocking if Quinn wasn’t in those D room meetings and game planning sessions. Of course he is, I’m sure Whitt gets his input.
It’s not working, as the actual play calling (game day) and execution (practice days + talent) is poor. But in terms of evaluating opponent tendencies and cooking up the game plan, I think it would be very surprising to learn that Quinn isn’t attending and actively involved in those meetings. Offense as well when they don’t overlap. But you can’t be a CEO style HC if you aren’t overseeing those critical meetings and joining in, it’s a collaborative staff after all. Something about the collaboration is bearing rotten fruit, however.
