OK, time to review how we got here.
The FBI was investigating someone for financial fraud (IIRC the stock market, but it's really immaterial) totally unrelated to college sports in any way, shape, or form. That person turned out to be involved with the Adidas people steering players to their schools. The FBI could then investigate it because the Adidas people, the families, and the coaches were perpetrating a fraud against an institution receiving Federal funds (such as Pell Grants). Making it worse, it involved wire fraud (because they used telephones and the Internet) and crossed state lines. They hit a Federal trifecta. I wouldn't b e surprised in the slightest if there are some "Conspiracy" charges thrown in because that's the Feds all-time favorite. They don't have to prove you actually did it, only that you and someone else agreed to to it and took an affirmative step to try to do it. Once something or someone crosses a state line, it becomes a Federal offense. They didn't target Adidas or any of the schools, it was literally dumped in their laps by going after the original target. While you can drag your feet and obfuscate (for 20 years in UNC's case) with the NCAA, you can't do that with the FBI. It is also a crime to lie to the Agents regardless of whether you are under oath or not. The schools and the NCAA have no say in how, whether, or when the case proceeds. Because the case is on right now, none of the materials that the FBI collected (e.g. the wiretaps) has been turned over to the NCAA. So, call for action against the schools by the NCAA are "jumping the gun" right now. Emmert doesn't need to be in the courtroom. He''ll get daily dumps from the news, etc. When all this is over the FBI will either give the materials to the NCAA or the NCAA will get them via FOIA since they become public records when they are entered into evidence.
I know SU fans have an axe to grind with the NCAA. I'm not a fan because they let UNC skate and I feel like I need to shower every time I have to defend them. But they do not have the investigative powers of the FBI and they will eventually get just about everything the FBI has.
