The Pi-Rate Ratings

The Big Ten Reverses Course

The Big Ten Conference has decided to resume football in 2020, reversing its decision to wait until the Winter/Spring of 2021. The league hopes to begin playing in late October and most likely play an 8-game schedule, concluding on December 19 with the Conference Championship Game.

This will pose big problems with the PiRate Ratings for two reasons, which I am sure the folks at Illinois, Indiana, Penn State, Ohio State, Michigan, Michigan State, Nebraska, Wisconsin, Minnesota, Maryland, Rutgers, Purdue, Iowa, and Northwestern didn’t consider when considering whether or not to return.

The PiRate Ratings will have to recalculate to a 90-team environment from a 76-team environment. Our ratings use sample size in the algorithm and maintain a mean rating of 100.0 (or 100.0 is par value). By the time the Big Ten commences playing, other teams will have played as many as seven game, and their updating criteria will be quite different from the teams just starting play. Even though the Big Ten will be self-contained and play only inside its own environment, for ranking and rating purposes, these teams must be compared on the same par value, which means in order to re-install the Big Ten’s original preseason ratings, the other 76 teams will have to be recalculated, and to be quite honest, not only have we yet to cross that bridge, we cannot find it on a map!

In addition to the recalculation, we will have to create new formats on our spreadsheets and input the new algorithmic formulae for 90 teams (or 76 + however many Big Ten teams play).

Note to Pac-12, MWC, and MAC officials: if you plan on reconsidering your league paradigm this year, please make those decisions known by Noon Saturday!
