"I really do, and he’s one of the best damn football coaches I’ve ever been around. I was hoping that him and I would be able to coach against each other in this game."

"He is one of my biggest mentors — I’ve got my dad, I got Larry Kehres (former Mount Union head coach) and I got Frank Reich. And Frank’s such a good football coach and yeah, you don’t want to know what I think of if he should be here or not but — because you guys can probably imagine what I really think."
