...and only 3 of them were in football. Years: 1969, 1988, 1991.
1969: Improper recruiting transportation.
1988: Improper entertainment, financial aid, lodging and transportation; extra benefits; out-of-season practice; complimentary tickets; improper recruiting entertainment, inducements, lodging and transportation; unethical conduct; institutional control; certification of compliance.
1991: FOOTBALL -- IMPROPER FINANCIAL AID: loans without a repayment plan. EXTRA BENEFITS: $6,700 from an institutional nonathletics fund; cash, loans, local automobile transportation and meals. IMPERMISSIBLE RECRUITING: cash payments by an institutional staff member. ACADEMIC ELIGIBILITY: graduate assistant coaches failed to meet minimum academic requirements. LACK OF INSTITUTIONAL CONTROL.
Only one of these 3 had lack of institutional control. I'd hardly call this a long, sordid history in rules violations, and I would wager a big bet that there is a lot less of anything going on at MN compared to schools with much larger alumni associations with heavier involvement in the booster programs.
