According to Bilas, the NCAA violated every rule it's ever had in the UNCheat case. I'm sure he thinks the same about UL.
Part of the newer friendlier NCAA is based on the concept that the school in question comes forward and is willing and able to self-investigate with honesty and forthrightness. The problem is that UNC has done anything and everything to minimize, misdirect and obfuscate at every turn, artificially hampering every 'so-called' investigation that has taken place.
For their part, the NCAA have been willing dupes, allowing UNC to coordinate and orchestrate what has largely been a farce. Even then, the watered down and limited Wainstein report has more than enough information to indict UNC. But never forget, the Wainstein report was limited ONLY to AFAM studies and he did little to no real digging into what the coaches and other athletic officials actually knew. There are plenty of other areas which have been deftly ignored by ONLY using the Wainstein report for the NCAA's consideration.
If UNC wants to claim that the NCAA didn't completely follow to the letter every protocol, then they can make that case. But the NCAA can, and should assert that UNC has been undermining the process the entire time, not just from the multiple failed investigations, the artifically limiting the Wainstein report to avoid other serious issues, the two-faced approach to SACS and the NCAA, the obvious delaying tactics and lame attempts at intimidation, propaganda and witness tampering etc.
Hopefully if this ever makes it to court, the NCAA will be able to demonstrate that it's UNC which has been subverting the process, and at the end of the day will do anything and everything to avoid taking responsibility for their own mistakes and paying for their misconduct.
