Really depends on whether Brown could step right in and understand his role at the NCB spot. If he could do it quickly? Then I would make that change.
I haven't focused enough on the Bears game to say how well he did or who Rogers covered vs the Bears in the slot. Looked to me like he did.. okay.. but I have seen enough of him trying to cover Amendola that I never really want to see him in the slot again. Brown has better balance and quickness for the role, IMHO, but who am I to tell Fangio his job? Rogers and Culliver seem more capable as outside CBs... but again.. who am I to tell Fangio his job?
That's just the way I see it.
