Haha. There isn't a lot of leverage threatening to fire a coach on a lucrative long-term contract. We can pay Doc to coach, or we can pay him to take a job with TNT while attending Duke games.
I can see the desire to get the younger guys more minutes -- I agree that it's important -- but those substitutions aren't going to solve our issues with rebounding, offensive execution, the vets (including Rondo) disappearing at times, etc.
