Not sure where the D went (although to be fair 14 points were not the fault of the D- punt return and that horrible fumble return), but from a schedule perspective I'm actually optimistic. There are basically 3 teams (GB, Dal, NYG) for 2 wild card spots. Here are the schedules:
NYG- @ WAS, CAR, @ MIN
DAL- @ NO, WAS, @ PHI
GB- @ PIT, SEA, @ ARI
GB is at 9-4 and I think has a good lock on one of the WC spots, however given the Giants schedule compared to the Dallas schedule, and the fact that we have the head-to-head tie breaker over them, I don't think it's out of the question for us to go 2-1 and Dallas to go 1-2 (at best).
The other consolation for the Giants is that even if we have to go 3-0, there is a chance that Minny will be resting their starters during the last week (with literally nothing to play for), so the odds of beating them could improve.
Even though we don't have a great team this year, I do see the possibility of winning a first round playoff game if we could sneak in due to the potential match ups (Philly or Arizona).
