I think Mike Brown is a good to great head coach. He has done wonders for defense for that team. Imagine if Mike D'Antoni was the head coach when Lebron got drafted.... he would of hurt/stunted his career. Look at Amare ...case in point.
D'Antoni is the opposite yeah, but a great coach would be like PJ, RA, Pop etc. JVG would do a way better job than Brown. he needs to be replaced whether they win a championship or not.
he doesn't have a clue on offense but he has the cavs playing good defense. they rotate, play help d very well, and are fundamentally sound. im not saying mike brown is an all time great coach but he is a good defensive coach that has his lack of offensive coaching shadowed because of a great scoerer like lebron.
