It took six years, but Ryan Day's Ohio State staff finally seems stabilized.
He was never going to clean house following Urban Meyer's planned exit after 2018, wrecking a perfectly serviceable transition - it's a big part of the reason only Greg Schiano, Bill Davis, Alex Grinch and Taver Johnson left the building.
Urban at his best needed specific types of guys to lean on and make the whole Urbanification of his programs work. Jim Tressel famously hired coaches who never made it anywhere else on their own unless another Tresselite was involved.
Day's preferred staff makeup?
