The OSU Natty over Miami was one hell of a turning point for that program. It can happen anywhere (see USC, Notre Dame, Bama pre Saban for a long, long time, you get the drift). Ohio State has been fairly resistant to going into a real tail spin over the years, Coop's 2-10-1 record vs. TTUN notwithstanding, so we've been very lucky.
However, we have had our share of bad circumstances primarily due to injuries like Keith Byers and Beanie Wells' foot, Ted Ginn's ankle, Troy Smith's growth of subcutaneous belly fat after winning the Heisman.......But we really, really missed going into an epic tailspin after Tress and *Gate (I don't even want to type out that damn 3 letter word in front of "gate") by hiring Meyer. BTW - I'm not ready to classify the significance of Brax's injury to this years' ultimate results. We know it is devastating to him and the team right now, but anything can happen, and JTB might just go full Krenzel mode.
For me, it's all about the head coach. Everything else flows from that: assistants, recruiting, fitting players to schemes, leadership. Get that HC wrong and your program goes in the shitter (see Michigan, University of). So, relative to Bama, perhaps the Kick6 and the hiring of Kiffin as the OC are chinks in the armor. As long as Saban's wife doesn't hit him in the head with a 5 iron because he was banging the waitress at the local Tuscaloosa Waffle House, they will continue to be formidable (dammit).
