the problem is that the types of personalities of players that were integral to 3 SB wins. aren't out there anymore. especially on the defensive side of the ball. there's no harrison out there, there's no bruschi or vrabel out there. so now that BB has to use himself as the mantra of the team, it ain't working out so well. kind of a difference between he and parcells. they have similar philosophies, but when he doesn't have the players to lead, parcells can grab the reigns and do it himself. I think this team is lost now.
part of the problem, I believe, is that when coaches go to a new team, there's a core group of vets that come along with him or players he had worked with as a coordinator previously to bring in a mentality that helps get the coaches point across. worked great for the pats and along with some good personnel decisions in draft and FA, cause the pats to win 3 SB's in the first 5 years. in the meantime, he never bothered to get involved with the grooming of younger players to adhere to the mantra that works.
it also helped to have 'player' guys like weis and RAC as coordinators. I guess part of the problem also is that you don't have a whole lot of charisma at the assistant level.
