Wierd. I don't see any mention of the following in the ESPN list, for example, yet the negative history of all of Woody Hayes, Jim Tressel and Urban Meyer are listed. Strange.
Tom Osbourne's issues off-the-field: https://www.nytimes.com/1995/09/14/sports/college-football-rash-of-arrests-has-nebraska-reeling-and-rethinking.html

Bobby Bowden's off-the field issues, and having to vacate NCAA wins. Florida State was also documented to have provided cash payments to several players on the roster, and NCAA investigation led to only a year of probation.
Lou Holtz: left every program he coached at just before they were hit with NCAA probation. NC State, Minnesota, Arkansas, Notre Dame, and South Carolina were all found to have violated NCAA rules while under the leadership of Holtz.
Danny Ford: Less than a year after Clemson won the national title, the NCAA banned the football program from TV appearances and bowl games for two years and took away 20 scholarships — sanctions for recruiting violations that took place between 1977 and 1982. The NCAA put the program back on probation again in 1990 — the penalty for 14 rules violations, ranging from cash payments to players of $50-$150 to improper recruiting techniques.
Phillip Fulmer: So many off the field issues that the Fulmer Cup created.The Fulmer Cup is awarded to the athletic program who plays the most convicts in a season, because Fulmer's teams were consistently loaded with felons.
