Pffft. NCAA only trying to look like they're doing something by nailing a program that self-reports violations. Hell, looking at established cheaters would take work, and if NCAA investigators wanted to work, they'd get themselves a job.
First of all, they haven't and won't nail ISU. Unless they find out that ISU is not completely disclosing the truth, the Clones are likely to get the two years of probation that they themselves asked for. Secondly, I'm confused about your point about "established cheaters" when the controversy that they are currently involved in is related to them busting an established cheating program and people getting butthurt about it.
2 years probation isn't nailing ISU? Do you understand the consequences if something ELSE should happen while ISU is on probation? It raises the level of jeopardy to their entire athletic department if something else surfaces, self-reported or not.
When I make mention of "established cheaters", it's collegiate programs where there are incidental or anecdotal disclosures of inappropriate benefits, or other violations of NCAA rules more serious than inappropriate contact with recruits. Here, I'd cite the absence of scrutiny of NCAA in the multi-year Penn State scandal, or their notable absence in the more recent Rutgers scandal. The information is out there, a good investigator can find it, but you have to look for it. NCAA prefers the shooting-ducks-in-the-barrel approach of investigating self-reported violations.
Yeah, I'm butthurt that the NCAA is patently ineffective. Probably shouldn't be.
