Last year, we debuted The Binion Index here at From the Rumble Seat. This power rating for FBS college football teams evolved from my rudimentary efforts to chart plays during Georgia Tech football games into a predictive metric that has solid predictive power.
Over the offseason, I’ve spent time looking at how TBI performed for each team from a win-loss and absolute error perspective. I expanded the range of metrics I was considering for evaluating teams, went through some variable selection algorithms, found an error in how I was incorporating schedule strength, and have deployed some changes that I am hopeful will make TBI even more useful for the upcoming season.
