And I am not saying the system is perfect...but both schools got a one year postseason ban. AND...both got it when they wanted it. Maybe Auburn knew their team wasn't great. But, Okie State had Cade Cunningham, and they appealed it because they knew they were going and pushed their ban off a year. They both "gamed" the system.
Edit: Also, a month or two ago, the NCAA released timelines on other investigations, including LSU and Memphis. Both of those schools have asked for deadline extensions multiple, multiple times. Both are using a delay tactic. Memphis thought it would have a good team this year, so they don't want a post season ban any time soon.
