You may not have heard it as this was before the internet, but traveling for work through the Midwest/upper Midwest in old B1G and Big 8 country - there were accusations from outside fans constantly. Iowa, Iowa State, Missouri, K State, Michigan, Wisconsin, and Colorado fans to name a few.
Accusations of county scholarships, rampant steroid use, bringing in thugs who couldn’t hardly graduate high school and having other students take their exams and/or willing professors give them passing grades, getting certain recruits laid / drugs / alcohol on recruiting trips, and so forth. Even the fans that had no examples would say - “there is no way a school in the middle of nowhere can have that good of a program without cheating. They are just really good at covering it up”.
I - like most on here - think these accusations are BS, but they were out there. Just like the Alabama, Clemson, and Ohio State fanbases would say our accusations are BS today.
