Well for one, his statement "our 4s are 5s and our 5s are 4s. They are interchangeable" is one of his issues. Not playing Vitor or Joel at the 5 last year, and not starting Zeller every game this year. Kelly and Sully are not centers nor is bass and neither should see the floor with the other 4s. Play big, JG can be at the 2, but not at the 4.
I have many issues with his game plan, but I'll wait till he has better pieces till I say fire him.
I mean many good coaches are without teams, Jeff Van Gundy, Mark Jackson, George Karl etc but everyone seems to want a young coach or an recent ex player like kidd and fisher etc.
