Sure but that doesn't mean the Pats go 6-0 every year against the AFCE. While the other AFCE teams might be a joke, they've gotten their fair share of wins against us. Here is a breakdown of NE vs the rest of the league from 2001 to 2018....As you can see, NE has beaten every division consistently and had the most trouble against the AFCW (a lot of that has to do with their struggles in Denver). If NE were in the AFCW or AFCN, for example, they'd probably lose 1 more game. not a big deal IMO.
Division Win - Loss Win Percentage
AFC South 41 - 9 .820
NFC South 17 - 5 .773
AFC North 32 - 10 .762
AFC East 83 - 29 .741
NFC West 14 - 5 .737
NFC North 16 - 6 .727
NFC East 14 - 6 .700
AFC West 31 - 16 .660
