Go 6-1 rest of way. Loss cannot be to Commanders.
49ers beat Philly
Beat Philly
Giants Beat Philly
Cowboys win tiebreaker based on division record
Yeah, the problem you have here is the Giants are positively terrible now. Philly could win both those remaining games with Mariota at QB.
The more likely, granted very slim, is hope the Eagles go into a slide here and lose to the 49ers, us and then on the road in Seattle. We win out or only lose to Detroit, and we'd win the division either with best record or best common games record (we'd have two common game losses - Cards, 49ers......... the Eagles would have three - Jets, 49ers, Seahawks).
The most realistic hope, and it's still not all that realistic, is the Eagles are about to go on a 3 game losing streak.
