From what I understand, he was the most hands-off he's ever been last year and we saw how that went.With as much experience as these two new coordinators have, I would hope he lessens his grip and allows more freedom for both sides of the ball.
I expect he'll let Grantham have almost total control of the D but it looks like he and Meacham have a specific plan for what they are trying to build on O. I think he will be involved in designing the O but you don't bring in 4 guys who've been OCs just to run your old system. I'm excited to see what it looks like.
