S&P+ rating: A team's offense-specific S&P+ rating, presented in the form of an adjusted scoring average. It is now presented in two forms: the first is a percentile, and the second is an adjusted scoring margin specific for this specific season's scoring curve. S&P+ rating: Using the five-factors concept above, the S&P+ ratings take into account efficiency (Success Rates), explosiveness (IsoPPP), and factors related to field position and finishing drives.They are presented below, with the difference between a team's wins and second-order wins in parentheses. This projected win total is a cousin of the Pythagorean record, a concept common in many sports. Second-Order Wins (2ndO Wins): Defined here and discussed in further detail here and here, second-order wins compare the advanced statistical components of a given game, and the single-game win expectancy they create, to the actual results of the game.

(A fifth factor, turnovers, is informed marginally by sack rates, the only quality-based statistic that has a consistent relationship with turnover margins.) Here are the components of the ratings shared below: The components for S&P+ reflect opponent-adjusted components of four of what Bill Connelly has deemed the Five Factors of college football: efficiency, explosiveness, field position, and finishing drives. All rights reserved.The S&P+ Ratings are a college football ratings system derived from the play-by-play and drive data of all 800+ of a season's FBS college football games (and 140,000+ plays).
