Before people say that tOSU won't get annihilated, here's Dohrmann's SI article that graces the cover of the upcoming edition.

It's not the bombshell the twitter world thought it would be, but there's some pretty damning and unsettling stuff in the article.
In my opinion, the resigning of Tressel should have no impact on the NCAA's stance on tOSU. It's pretty clear that there's been a LOIC at tOSU for quite some time. Whether it was Clarett, Smith, or the TattooFive (which may actually be more than five), tOSU has done little to steer their institution away from these allegations over the past decade.
Examining the evidence that the NCAA presented to the COI against USC, it's pretty clear that tOSU's evidence is far more damning and knowable. By that, I mean that they can actually and unequivocally say that Tressel had knowledge and opted not to report it. They were never actually able to tie anything of substance to Bush. (Sorry, I do not take the word of a convicted felon, whose story was never checked out, verified, or subject to cross-examination, as substantive).
The COI hasn't had much of a problem railroading universities despite the departure of the coach who was there.
Also, people seem to think that this is Tressel's first go-around with improper benefit allegations. These allegations are part and parcel of what he was a part of during his days at Youngstown St. I find it hard to believe that the same exact problems occurred at two different universities, under the exact same coach, and he wasn't aware of it, or lacked the control to do something about it.
As close as these players claim to be with Tressel, it's impossible that he wasn't aware of this stuff. I mean, the NCAA is going to have a very hard time convincing me that he "had no knowledge." The only reason the NCAA wouldn't hammer tOSU on this issue is because they would have to admit they dropped the ball by allowing those players to play in the Sugar Bowl this year. I don't see them doing that.
