Doc put in the hard yards the early years with Orlando and the Celtics, he knows the system, used the Championship on his resume to get that dual role with the Clippers and a pay upgrade, I don't blame him for not wanting to go through another rebuild.
Once you have had that level of success why take a step back, There is a reason that some coaches take a year off or two and wait for a better opportunity to come their way.Just happens that his happened while still under contract.It all worked out for the best in the end.
It is a good strategy to follow.
He gets guys to play hard for him for the most part and doesn't appear to lose many locker rooms.
My only issue with the guy is that he is a talker.
