Ah, the world is more random than we all like to believe...and sometimes it moves in our favor, which is always nice. The Eagles late-season and playoff run may seem pretty improbable - but I don't think it's nearly as improbable as many believe. The fact is that football is not played in a series format, so with such a small number of games, the so-called "improbable" occurs relatively often.  The lack of a large number of games per season, and especially in the playoffs, means that even when one team is materially better than another - the certainty that the better team will win is pretty low.

If you take this logic further - the Titans weren't as good as they seemed all year, the Lions weren't as bad as history will judge them, and unfortunately the Cardinals have almost as good a shot to win this game on Sunday as the Eagles do.
