Likely unpopular opinion, but I don’t care.
I never liked Bobby Knight and never had respect for his coaching style and inflated ego. Just not for one for the drill sergeant style of beating and cussing players into submission. By contrast, Josh Heupel, Rick Barnes, and Tony Vitello are precisely the types of coaches who not only pull the most out of their players, but earn respect in the right way.
Going back further, Pat Summitt was a tougher coach, but those players always knew she loved them and wanted the best for them, and they loved and respected her because of it.
