Scott Brooks has to be fired. It's not just that the offense isn't good, it's that it isn't getting any better either. He's not learning.
You look at guys like Pop, Carlisle, and Doc, and what distinguishes them is that they get better every year. I watched Doc coach the Celtics for three years, and I thought his work with the Clippers was better than any of those Celtics teams from an X's and O's standpoint. The Spurs offense was great least year, but this year they have more great sets and they run them better. The offense Carlisle ran this year against the Spurs was insane. He made Ellis look like a superstar. These guys are great because they never just decide what they've already figured out is good enough.
Then you have the Thunder, who can't run a counter if their first action is stopped. Again. What's the point of keeping Brooks around?
EDIT 2: Or look at Jason Kidd. At the beginning of the season he sucked. Even though the Nets lost to the Heat in 5, they found an identity, were motivated, and ran good stuff on offense and defense. Brooks has only kinda found an identity for the Thunder, is admittedly good at creating a culture, but is very lacking in terms of the system he implements.
I just can't understand why it isn't a foregone conclusion he will be fired.
