i can't argue too much with this, and i especially agree with the bolded. i don't think you can build on a culture model. culture is important, but it's something that developed every time. I don't think BB walked on as the coach of the pats and just installed a culture. they landed on a qb, but systems in place, kept consistency, and the winning culture appeared.
my hope for this staff is that the offseason is drastic. they put themselves in this situation, so i'm very curious to see if they can get themselves out of it.
