Look at the playoff teams they played this year. I'm sure they're among the most challenging sched among the playoff hopefuls. Just brutal. 7 games against playoff teams by my count and they have one of the best records in the league.
This year's team is kind of amazing. They're not as dominant in the pass game as I expected. But they're more stout running the ball and stopping the run than I anticipated which is actually very nice for the playoffs. In fact I think the sched helped shape that. If they play an easier sched maybe they're still in pass happy mode and ready to be hit in the face in the playoffs.
Now though... I think they are battle tested. I think they're tough. And I think they have a chance.
