Ohio State has suffered 4 losing seasons in the past 68 years!
That would suggest there's little risk of them suddenly becoming another Rutgers regardless of who's picked for their new HC imo.......
Ohio State will never fall to the recent Rutgers level, but it's not inconceivable that they could have a dip similar to what Michigan experienced under Hoke and RichRod.
Ohio State did go 6-7 (with a loss to NU) in their transition season between Tressel and Meyer, though those circumstances were a bit different.
