How about 7 teams going 14 2 spread across one conference I believe that is possible too Take DAL PHI MIN GB NO ATL and ARI Assume NFC E is matched against NFC S DAL PHI split their games and sweep the other four divisional games Both must play NO ATL so they split those games as well That s two losses for everyone They avoid playing the teams mentioned above in the one game they need to play against the NFC N NFC W and they sweep AFC opponenets Its a stretch but possible unless I missed something
