Not sure of all you read about Holtz and he is I am sure good in many ways. But I am not sure about inspirational in all things and what is important.
From a Bleacherreport web page below after searching for "lou holtz coaching infractions" it has also been known for a long time how he skirted the rules and basically cheated or kept quiet about things. Cheaters are not high on my list of top coaches and inspirational people. (And he bailed on the Jets at the first sign of tough times with a terrible terrible 1976 campaign where he tried to bring the veer running offense from college to a pro team and he admitted he never watched or knew much about pro football. He was chasing a bigger paycheck.)
Lou Holtz is typically not thought of as a dirty coach, but has 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.
Holtz was also overseeing the Notre Dame Football team when they were caught distributing steroids in the locker room during the late 80’s and early 90’s. The NCAA allowed the Irish to handle the matter internally, but there is no way Holtz was unaware of all that was going on with his program.
Holtz should go down as one of the most successful coaches in the modern era of football, but should not have a blind eye turned to the legacy he left at each school he coached.
