I am one of the diehards who have followed and attended Celtics games the past 10 years when they were horrible and rebuilding. I have especially paid attention to Doc Rivers during the Al Jefferson era, and without going into it too much without making my head explode, he's a horrible coach. The fact that the Celtics are 20-2 right now, just goes to show how much the NBA is a players league and a star league. Basketball is like the opposite of football, where the coach is way more important. In basketball, if you have 1 superstar, or 3, then it doesn't matter what the coach does.
