I totally understand what you're saying, but I disagree.
To me... the "In BB We Trust" mantra doesn't say 'I have no mind of my own'. To me it says no matter how much I dig, read, and learn, I will NEVER know anywhere near what Belichick and Pioli know.
I will never know how a player in the draft will truly fit in with the plan for the Patriots this year, or next year, or five years after that. Hell, I don't even know what the plan is. None of us do.
I will never truly know the state of the roster at hand. Is Michael McGrew (picking an unproven WR at random) just training camp fodder, or has he somehow shown the spark that tells BB that there's a Givens-like light at the end of the tunnel that nobody else saw? I don't know, and neither does anyone else here.
There's just so much we as fans don't know, won't know, and can't know. All those things which we don't know, by necessity, our management/coaching staff DOES know. So it comes down to the question, who do you best trust to handle the things that, as a simple outside observer and fan, you aren't privy to? Can there be any other answer than Bill Belichick?
No matter who's in the driver's seat, we'll NEVER have all the information, all we'll have is speculation on our part. So the question becomes, to me, who among all the NFL coaching and management, do you trust to make decisions based on information you and I don't have? Personally, the answer there is, "In Bill Belichick I Trust". Above all others.
Is the BB/SP team infallable? Are they perfect? Duane Starks and a bevy of others testify, "HELL NO!". Do I think there's anyone better at making these decisions based on information I don't have? Hell no.
I'm no sheep... but In Bill Belichick I Trust.
