Did NU not get exposed for its basketball players shaving points in games and being paid to do so?
And not too long after that, did NU not get exposed again for its football players betting on their own games?
I don't think NU is a cheating cesspool because some of its players cheated. Especially since the institution responded in the right way.
And I don't fault UT because one its coaches held a barbeque at his house, and then lied about it to the NCAA (that was Pearl). Because the institution responded in the right way.
By the way, Tyndall did nothing wrong while at Tennessee; you seem to be claiming he did. And Kiffin (God, I truly dislike that man-child) had only minor recruiting violations of the nature that happen throughout just about all programs from time to time (texting a player in a recruiting dead period, etc.). You wrote your sentence as if Tennessee hired three thugs and set them lose on the NCAA rulebook. Gross mischaracterization, if that's what was intended.
Actually, the football player gambling happened before the basketball incident, but what you are pointing out actually underscores why NU is different from dOSU and most if not all schools of the SEC. We were actually lauded by the NCAA and the FBI for how we handled these incidents and held up as a shining light model for all. We don't hide anything, try to cover it up, much less institutionalize fraud, cheating or anything inviolation of NCAA regulations or criminal law to get ahead on the football field. Every school is gonna have some rotten apples, some more than others. It's a question of what the school does to foster an environment that minimizes these unfortunate incident, manages them when they occur, vs. trying to cover it up, look the other way or even outright encouraging or facilitating them.
