UGADawg4Life, do you mean the dirtiest programs currently or historically (i.e. all-time)? In either event, Auburn and Alabama certainly are serious contenders for top prize on this Wall of Infamy. According to this source (
College Football (FBS) and NCAA Probation » FootballGeography.com), however, the following programs are historically the most penalized:
1 Southern Methodist (TX) 17 seasons 7 times (Bowl Bans: 1964-65, 1974-75, 1981, 1985-86, 1987-88)
2 Southern California 15 seasons 6 times (Bowl Bans: 1956, 1959, 1982-83, 2010-11)
3 Auburn (AL) 11 seasons 4 times (Bowl Bans: 1956-57, 1958-60, 1979-80, 1993-94)
4t Alabama 10 seasons 3 times (Bowl Bans: 1995, 2002-2003)
4t Michigan St. 10 seasons 3 times (Bowl Bans: 1976-78)
4t Oklahoma 10 seasons 5 times (Bowl Bans: 1960, 1973-74, 1989-90)
If you want to use bowl bans as an artificial measure of the seriousness of infractions, SMU, Auburn, and USC would be, in that order, the dirtiest programs in college football history.
