Here is one other opportunity that opened up after after that Giants lose last night.
1. We have to win out, PERIOD.
2. Seattle must lose against two of their remaining three NFC opponents, or Chicago loses three of their last four, all NFC oponents. PERIOD.
3. If the first two occur, meaning we beat the Giants giving them their sixth loss, then Giants must lose against one more of their remaining two NFC opponents (@Atl, Philly).
This scenario may be the more plausible since we would then have the tiebreaker against NY, which we do not have against Washington.
