As an initial thought, I would like to throw out there that although Baltimore has had a great season, the argument could be made that until this week at Tennessee, Baltimore has not defeated a good team all season (with all due respect to Miami). Here is Baltimore's schedule and results this season.

The only playoff teams they beat were Miami and Philly, and they caught Philly at home and at the right time when they had hit rock bottom and McNabb was benched. They lost to PGH, NYG, IND and TEN - and the NYG and TEN games were not even competitive. The rest of Balt's schedule was a joke - Jack at home when they had given up, Cincy and Clev twice, WSH and HOU (same as PGH), OAK at home.
