BB is a very controlling person. He'll never have the type of delegation Parcells did, it's not in his personality. Both RAC and Weis had the unique attribute of being outsiders that were insiders, but you are correct. However, having his trust allowed them to add to the team rather than being appendages of Belichick (my presumption here).
You are very right, and i mention it often, that we are fortunate to have a coach/exec who puts the future of the team first and always fields a competitive team. To me, this is the major factor in success. If you bet the house on a season, then collapse for two or three, your chances are slim, because stuff happens.
I'm a little concerned because i basically agree with everything you posted.
Why am I basing BB? I'm not. Red Auerbach had faults. **** Williams had one year. I tried to make a subtle point, and i get "what's your point"? so I exaggerate.
Bottom line is, Belichick is a detail guy, he's a worker. He doesn't leave things to others. Sometimes a fresh perspective from someone you trust is what you need and he is not one that likes to delegate. BB alluded to this in his day after season presser.
That's why I think the Corwin Brown signing could be significant. It might be that, given his personality, a known player and coach who's also been elsewhere could be effective.
It's management style. Hate to bring up Parcells, but it's instructive I think. BB and Parcells personalities are opposites, detail guy big picture guy. BB has modeled Parcells at various times, he is his biggest mentor, like it or not. Problem is, what works for Parcells personality is usually terrible for BB's, since they are opposites.
Belichick admitted in Cleveland he was trying to be tough guy Parecell's. doesn't mean he isn't tough, just means sarcastic wise cracking abuse of the press ain't him (I could be mis characterizing, but BB historians know he said he made a mistake trying to be Parecells in Cleveland).
Years later, having coaching retirements and defections, he goes to the Parcells model of grooming talented young coaches. Difference is, Parcells taunts his coaches, and is all too happy to delegate work to talented younger coaches. coaches get a "I'll show him attitude" and excel.
I think we have a lot of hard working coaches who feel that doing what BB wants is what brings home the bacon. I doubt they see any reason to prove anything or come up with different ideas, no one out works BB, no one is smarter.
I'm sure people will nitpick this and ignore the point (BB had jobs before Parcells!), that's fine i won't respond unless you want to take time to get the point and disagree.
Like I said, BB referred to this phenomenon (organizational go along group think) and I think Corwin Brown is a good step.
