I feel like any of the four remaining teams can win at this point. The Pats are a mystery for the reason roubaix said - they've reached an extremely late point in the season without beating literally anybody good. They *seem* to be a good team, and Tom Brady is a Hall of Fame quarterback with an unbelievable set of receivers, but they have one of the NFL's worst defenses.
Two other teams with stellar offenses and porous defenses went down to defeat this weekend. New England had the fortune to play a team that really shouldn't have been there.
It's a four-team tournament with four good-but-flawed teams. Should be pretty good.
