ESPN 30 for 30-Trojan War or Rebel Down?

Last night my wife and I watched the 30 for 30 program that outlined the reason for the USC Trojan's downfall. As we watched, my wife, who is a casual football fan, mentioned that the Trojan's problems sounds alot like the Rebels current situation. After the show, I tended to agree with her. Here are the similarities:

USC burst on to the scene in recruiting after 20+ years of mediocrity
Pete Carroll saw several of these recruits going in the 1st round
After 2 Natty's (Reb's haven't won shite), rumors on players being paid
NCAA begins investigation into the program
Investigation almost completed, learns Bush's mom & step-dad receives money.
Opens a new investigation in Bush's ordeal
NCAA starts looking at a possible "Show Cause" for Carroll
Carroll gets his own lawyer. (Sound familiar)
Carroll gets the hell out of dodge and goes to the Seahawks.
At this point, USC was ready to take the original NCAA penalty of 1 year post season Bowl ban, 6 loss of scholarships over 2 years and a maximum 82 scholarship players over two years. After the Bush findings, the NCAA had other plans for the Trojans.
The NCAA handed down loss of 30 scholarships over 3 years, a maximum of 75 scholarship players and a two postseason bowl ban. In addition, they vacated all wins in 2005 !!
The NCAA cited that if it wasn't for a disgruntled prior agent(sound familiar) for Bush, they would not have known about the money going to his mom & step dad.

Hey, maybe the NCAA has new blood on the committee and they won't be as harsh as the one less than 10 years ago. Maybe the Tunsil and Bush comparison is a stretch. However, I would think that getting money from OM coaches is a hell-of-a lot worse than getting it from an agent.

A key USC official summed it up at the end of the show when asked about the hammering from the NCAA, "When they spend all those years, time and money investigating us, you know the penalties are going to be severe"

How long have they been investigating OM and they aren't done yet?
