Bob Knight was an abusive POS.
John Wooden won 10 NCAA Titles, abused no one, and threw zero chairs.
Red Auerbach, Phil Jackson, etc…
He may have ended up that way, but he wasn’t always like that.
Personally I started being troubled more when he started doing things to players like Neil Reed…who by the way once lived about 10 miles from my house. Neil’s dad was head HS coach who rumor had it abused his son Neil Reed. I worked with a guy that was his teammate and he as punishment when Neil had a bad practice he would make Neil walk home even on cold, dark December and Jan nights. Then Neil went to IU and was abused by Knight, sad.
Bobby ran a squeaky clean program, when he was surrounded by crooked programs like U of Kentucky and later Louisville. UK was so crooked they dropped bundles of cash on the floor being given to players which is how they got caught once..”Corrupt Arena” was more accurate than people know. Knight also helped his players graduate at high rates and was supportive in other ways.
But yes like I said his anger dominated his personality as he aged.
