Congratulations to Notre Dame Football! Ranked Number 1 in Final Postseason Poll:

Congratulations are in order to the Notre Dame Fighting Irish for finish the season Ranked Number 1 in the final  Colley Matrix Computer Poll.  The Colley's Bias Free Matrix Rankings is one of Six Computer Polls used in the BCS Championship Polls ranking system.  This is at least the 9th National Championship for Notre Dame's Football program, tying them with the most All Time!
 Colley's matrix method for ranking college football teams based on very simple statistical principles, and uses only wins and losses as input—margin of victory does not matter. The scheme adjusts effectively for strength of schedule, in a way that is free of bias toward conference, tradition, or region. Comparison of rankings produced by this method to those produced by the press polls shows that despite its simplicity, the scheme produces common sense results.

This method focuses more on "deservedness" to play in the national championship game than it does predictiveness, per se, which may be of more interest to some fans and bookmakers, who often consider margin of victory, injuries and other factors in assessing the possible outcome of a particular game.
