Also from that, for everyone saying Fickell is the one responsible for that defense, not Ash:
If Ash leaves, the Ohio State defense is in much better shape than it was two years ago when Ash arrived. Meyer zeroed in on the style of defense he wanted to run and found a coach in Ash who ran it. Ash has said he wouldn't have come here if there wasn't agreement on that.
The Buckeyes have a co-coordinator in Luke Fickell steeped in this style now, and whatever Meyer would do to replace Ash, the defense isn't changing. It's going to be aggressive man coverage. Fickell could run that as the solo coordinator if Meyer hired a younger secondary coach. Or Meyer could bring in someone to share those coordinator duties again.
Ohio State would not have won the national title last season without the way the defense played, and Ash deserves a ton of credit for that. So does Fickell and every player on that defense, as well as Larry Johnson and Kerry Coombs.
Then the defense got better this year.
Ash would be a major loss. But at least right now the Buckeyes know what they want to do on defense and how to do it. That won't change.
Sounds to me like Meyer brought in Ash specifically to install this style of defense.
