>>He was not fired until after he publicly disagreed with the school’s statement about the game. This is most likely the reason. Whether or not he was truly fired for winning by ‘too’ much is a matter of debate.<<
I think you’ve hit the kernel here.
This is not about basketball. Basketball was merely the spark.
Who expects to do their job well and then be publicly excoriated for it by their employers? He just returned fire. He was right to do so.
As to the score... would it be ok if he only won 50-0? Or would it have to be 20-0? or does he need to let them score? See where this is heading? It’s a slippery slope with nothing but “feelings” to guide you. It’s a symptom of a sick society that so many people want to criticize and penalize success.
