= Strength of Record = Strength of Record (abbreviated as SOR) is a statistic developed by ESPN that measures the probability of having a given team’s record at that week in college football.

SOR is calculated through a poisson binomial distribution, classifying a vector of probabilities for an average top 25 team. It cares less about a team’s Win-Loss record and focuses more on how they were able to achieve that record, based on the amount of rest, difficulty of schedule, and other factors. In addition, SOR incorporates ESPN’s Football Power Index for predictions of SOR.

SOR has correlated well with the four teams that have made the college football playoff each year. ESPN calculates the probability that a team’s SOR will be in the top 4 of all teams in the FBS. Teams that have made it in the top 4 of SOR have made it to the college football playoff 11 of the 12 times.
