League Adds Game 17. Titans vs Saints

I misunderstood you as well. You’re saying that the entire AFC south is each playing 1 NFC south team not saying the titans play the entire south division.

I don’t know if the 17th game against the saints is actually week 17 though. I expect the final 2 weeks of the season will be divisional rival games pretty much across the league like it has been.

 

NFL owners ratify 17-game schedule for 2021 season and here are the changes coming

 

This also clarified what I was suggesting about the 5th non conference game being determined by the div position finish of the year before AND

All AFC teams get an extra home game this season which will rotate every year back and forth afc/nfc.
That’s about the best way I could expect the extra home or away game to be decided.
