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 W/L 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. ESPN calculates the probability that a team’s SOR will be in the top 4 of all teams in the FBS. Thus, SOR looks at teams that are "most deserving" to be in the college football playoff.[1] In addition, SOR incorporates ESPN’s Football Power Index for predictions of SOR.
Strength of record is a backward-looking measure of team accomplishment. Unlike ESPN's Football Power Index, strength of record does not care about how a team won its games; it simply cares about the difficulty of a team’s schedule and the result (win or loss). Based on the results of which teams have made the college football playoff, the playoff committee appears to side less with FPI and more with the most deserving teams, hence SOR.[2] It has correlated well with the four teams that have made the college football playoff each year. Teams that have made it in the top 4 of SOR have made it to the college football playoff 11 of the 12 times.[3]
