I have a book titled “Down and Dirty” about Oklahoma football under Switzer. It was written by Charles Thompson a star quarterback on the team.
To make it short, it was probably the most corrupt program i the country. Basically it was totally corrupt. Thompson was also recruited by Oklahoma State and it appears they were just about as bad at the time.
I think the current OSU team under Gundy is probably OK. Maybe the same about Oklahoma now but I don’t know.
No doubt Switzer was not a saint, he’ll even admit it (something JoePa was never willing to do).
