There were a lot of abusive coaches in the 60s and 70s.
I think part of the reason was so many men being in the military.
Some guys could dump and vent on players under them under the cover of discipline and "what's good for them."
Remember Captain Herbert Sobel (David Schwimmer) in "Band of Brothers" and Lieutenant Commander "Captain" Morton (James Cagney) in "Mr Roberts"?
There were real people like that in miserable circumstances.
Knight was in the Army and was head coach at USMA from 65-71.
Back then hazing at West Point was not only allowed but was considered part of training.
Everybody could dump on everyone under them in a chain of ranks/classes.
I can imagine a volitile Knight coaching at Army and getting away with stuff.
Lombardi was another tyrant who- as he was dying of cancer - had remorse for the way he treated players.
There were others like Bear Bryant (Navy in WWII) and his "Junction Boys" abuse.
Woody Hayes was another volcano and he was Navy in WWII (commanded a PT Boat)
Of course there were good guys like Tom Landry who co-piloted a B-17 for 30 missions as a 20 yr old. I don't blame the military specifically - just that it allowed some people to take liberties and get bad habits
I had mostly good coaches in HS but it was a time you were not allowed to drink water during Augst two-a-days. That sort of thing was the "torture as good for you " vibe.
Coaches were very poor on teaching techniques but great at whistles/sprints, Oklahoma drills, "hit-its" and such. We had an assistant coach that would smack guys helmets and wrench their cages and he was a Nam paratrooper.
Speaking of hit-its (you jog and hit the ground on command) - I was made to do 100 of them at 2AM as a 16 year old at a summer football camp. Nobody could get away with that today
Bull in the ring, Oklahoma and others have gone out of style for safety concerns. 'It’s a wonder we’re still alive,' says current high school coach.
