There's 3 divisions in the NFC which could come down to tie breakers.
SF/SEA could both end at 12-4 should SF lose to LAR but beat SEA and SEA beats AZ and loses to SF. Both would have lost to Ravens and Rams and to each other. Both lost to a common opponent from the NFC south in NO for SEA and ATL for SF. So, next tie breaker.
GB/MIN have a head to head left which would them put both teams at 11-4 if Minny wins. If they end up tied either at 11-5 or 12-4, common opponents outside division are AFC West and NFC East. Final game each is a division game, so still common opponents. To end up tied, GB has loses to PHI, LAC, SF, MIN. Min would have loses to CHI, GB, KC, SEA. Common opponents that they would have lost to would be LAC/PHI for GB vs MIN with CHI/KC. So, would go to the next tie breaker. GB would have the better Division record.
DAL/PHI both 7-7. To be tied, both need to be 8-8, as PHI needs to beat Dallas but lose to NYG and Dallas would then need to beat WAS. Dal loses in that scenario would be to: NO, GB, NYJ, MIN, NE, BUF, CHI, PHI. Philly loses would be to: ATL, DET, MIN, DAL, NE, SEA, MIA, NYG.
Common opponents outside the division are AFC East and NFC North.
Dallas common opponent loses would be to: GB, NYJ, MIN, NE, BUF, CHI.
Philly common opponent loses would be to: DET, MIN, NE, MIA, NYG.
So, if Philly beats Dallas in week 16, do they wrap up the NFC East?
