No.
Every DIVISION game is a MUST WIN.
You might be able to fark up NFC games and to a certain extent AFC games (although they matter more due to overall conference records in tie-breaking situations).
But AFC EAST DIVISION Games are ALL must-win games since they usually matter the most when it comes to playoff seeding/tie-breaking. Period.
Two years ago we beat the Jets in both regular season games. They went to the playoffs and we didn't.
Your premise just isn't true. It simply isn't a must win. It isn't anything close to a must win.
