Luke (not by choice) shouldered a heavy load as an interm coach and did not have a winning season. From that moment on, he had a tainted legacy.
I fail to put all the blame on Fickell. He was our ST coach in 2002-03 when we had arguably the best kicker in OSU history. He was also the LB coach in 04 and became the LB/Co-DC coach from 05-10. Think about those tough silver bullet differenders that walked through Ohio State from 05-10 - Hawk, Jenkins, Carpenter, Schlegal, Laurinaitis, Freeman, Coleman, Anderson Russell, Homan, etc.
The guy knows how to coach up some great defensive players, linebackers in particular. If you want to blame him, then blame should also go on Withers because we have a track record for Fickell here; but we don't have a clue as to what good Withers can provide at Ohio State. Coombs also is a great coach and recruiter but again all we can do is base the guy on the last two seasons of DB and ST play. Neither of these have been something strong for the Buckeyes.
Lets remember something when talking about this defense. Going into the B1G CG, the Buckeyes were a nationally Top 5 Rush Defense and #1 in Sacks. The weakness was in the backfield. Sounds to me like its mostly a backfield coaching issue. Im not going to have surgery done on my broken arm if my leg has a bullet in it. You attack the immediate wound and go from there. That said, Im not sure what taking out Fickell will do.
Maybe next year we have 1 HC, 1 DC, and 1 OC, non of this "co" crap.
