Frazier’s defensive schemes lacked aggression and failed in the post season because he coached to not lose vs coaching to win, it became very obvious during the last couple of seasons, he stated that he disliked making in game adjustments, because he thought he would lose the respect of his players, (he said as much in an interview) when the reverse was the reality. LF is a good guy, but he had to be let go for the greater good.
