The fact that he was a bad person to his students is what seals the deal for me. Plus how you gonna truly critique someone when you can't do it yourself. Like that fat lady who teaches kids how to dance on tv, can't take her serious. Demeaning people under the guise of training/teaching is bogus. I've been a supervisor for years at a previous job, there is a way yo get your point across without being a ****. Otherwise that person should try an alternate profession.
You do realize that most great coaches in NBA history either
A. Didn't play
B. Were "bums"
The, "If you can't do it how can you teach someone else card" doesn't exist.
Plus, who is to say he is teaching them moonsaults?
