Meh, not sure I agree. Losing on the road to a divisional opponent can happen, even when you are more talented than them. The Brady Patriots had a relatively poor record in Miami actually.
Despite mainly facing three inept franchises I think the Patriots dynasty swept the AFC East just five times in 20 years.
I think the Falcons is our worst loss of the year. 100%. The Patriots one hurts most in terms of impact on the season, but the Falcons defeat was diabolical.
