I don't know the answer, but I'm curious as to what non Pats AFC teams record outside the division is (Brady era), and then compare it to the other non 1st place teams outside their division in the same time frame. Would it be that different? I honestly don't know.
I guess I'm asking how bad have NYJ/Buff/Mia been once you remove NE from the equation. Are they that much worse than say Min/CHI/Det or whatever other group in the same time frame? Again, I don't know, but my hunch is that the discrepancy wouldn't be as big as you'd think.
