A Bayesian Mean-Value Approach with a Self-Consistently Determined Prior   Distribution for the Ranking of College Football Teams
  We introduce a Bayesian mean-value approach for ranking all college football teams using only win-loss data. This approach is unique in that the prior distribution necessary to handle undefeated and winless teams is calculated self-consistently. Furthermore, we will show statistics supporting the validity of the prior distribution. Finally, a brief comparison with other football rankings will be presented.
