Why haven't any of his assistant coaches went on to be successful coordinators elsewhere?
Why do they all look like bums the moment they leave his immediate orbit?
The idea that no one else in the organization contributes is silly. But BB isn’t looking to hire assistant to groom them for elsewhere. He is looking for folks that fit the patriots system. Doesn’t mean they will fit elsewhere. Putting a Lamborghini transmission in a ford focus won’t improve the car, in fact it might not run at all. Putting a coordinator that has only operated in a highly efficient system in a dysfunctional one and he will be less able to cope with the dysfunction than someone use to an inefficient system. I had a coworker with 20 years experience in the army who absolutely could not cope with the lack of documentation and formal procedures. There was nothing wrong with him as a person, employee or tech and in fact he did a ton to improve the department in the six months before he quit. But he just couldn’t cope with our level of disorder.
But I think the real key is BB has earned him a level of respect that allows him to act in a way that when he does it every one accepts it and when other copy it they are viewed as arrogant and foster a mutiny.
BTW i am not advocating hiring NEP coordinators. It is tiresome seeing so many good ones leave.
