I’ll start by saying I’m not emotionally tied to any coach. They are all pricks, at least the good ones anyway. Mullen probably just meant to say he’s the best DC I’ve ever had, and he would probably be right. Anyone that can get that level out of last year’s roster deserves a tip of the cap at least.
Do I think Grantham is solid? Yeah. Maybe Semi-elite. He is hanging his hat on sacks and turnovers, for sure, which can lead to a lot of opportunities on offense. He is also incredibly stubborn, which is a great asset until it isn’t. Could we do better, maybe, but the better pool is small and the worse is an ocean.
