New York going 3-3 and Philly going all the way into the tank is not unrealistic.
You're right. Washington, Dolphins, Jets, Panthers, Vikings, Eagles. 3-3 is possible, maybe even likely, though the three losses are probably non-divisional leaving the Giants at 4-2 in the division. If we finish 8-8 and sweep Washington, we have to hope the lone loss is to Buffalo or the Jets.
If we finish 8-8 (i.e. go 5-1) with a loss to the Panthers, then the Giants probably win the tie-breaker. For that 8-8 scenario to play out we have to pray for 3-3
and at least one victory from Washington or Philly.
Likely the season is on the line today, just like we thought.
