I don't see any games on the schedule besides may be Pittsburgh that are certain losses. The schedule is crazy easy, I would be disappointed if the team doesn't win 9-10 games.
I don't expect playoff success even if they make it that far, but the defense is essentially as healthy as it's been all season (Urban is really the only guy missing). The offensive line is gelling. The running game might be for real. Flacco needs to play well, but I think he has been solid this year.
Once you're in, you never know what happens. Teams can get hot. Even bad teams have made runs in the postseason, especially fueled by a dominant defense.
