Unless these claims can somehow be corroborated independently then nothing will come of this. That was how they nailed SMU in the 70's. They got the stupid president of the school to admit on TV his handwriting was on an SMU envelope addressed to a player who was gettin' payola to playola.
They also had corroboration in the Reggie Bush case too.
I know alot of folks think "the barn" as the NCAA givin' them a pass these days and what with the Cam Newton escapade who would blame them. But during the 70's and the 90's AU got nailed by the NCAA and but good for similar scandals.
Those of us wishing for Auburn to get the "death penalty" can forget it. Given way that SMU football was literally wiped off the map in their "death penalty" case, the NCAA is likely to be very hesitant about that option ever again.
And also be careful what you start asking for if you are a fan of the SEC. Seems I recall that not long after the SMU case many other schools were put on probation from the SWC, having been turned on by their SWC brethren and about 15 years later that conference came to an end.
