Total quarterback rating ESPN's total quarterback rating is a proprietary statistic that was introduced in 2011 and is designed to measure the total effectiveness and performance of a quarterback. The metric takes into account all of a quarterback's contribution to a game, including passing, rushing, sacks, penalties, touchdowns, and turnovers. Moreover, each play is weighted based on its "difficulty", the context of the game, and the strength of the opposing defense. This means that statistics in garbage time of a blowout game hold less merit than statistics in a close game. Also, a quarterback who throws for four touchdowns and 300 yards against a strong defense will have a higher QBR than a quarterback who has the same stat line against the worst defense in the NFL. It is also very common for there to be significant differences between QBR and passer rating leaders due to the additional variables and situational play context that contribute to the calculation of QBR. For example, in 2019,
Lamar Jackson had a league leading QBR of 83.0 and earned
MVP honors. However, in terms of passer rating, Jackson (113.3) finished behind
Ryan Tannehill (117.5) and
Drew Brees (116.3), who finished ninth and third in QBR, respectively.
PFF Player Grades Pro Football Focus (PFF) is a football website that conducts in-depth analysis on NFL and NCAA games and players. Part of this analysis involves assigning each player in the NFL, as well as the
Power Four at the collegiate level, a grade that indicates their performance. According to PFF, the group's algorithm analyzes every play for each individual player and measures the impact that said player has while on the field. A player's impact is then given a grade between −2 and +2 in 0.5 increments. Each position has a scale with a unique algorithm and rules. The scale also takes into account game context, so a strong play in the fourth quarter of a close matchup will be graded higher than one in the 2nd quarter of a blowout game. A 0 player grade on any given play represents any position player performing at an expected level and in a manner that neither positively nor negatively impacts their team. An example of this is a running back taking a carry through the correct hole and picking up three to four yards in a
1st and ten situation. Meanwhile, a +2 represents an incredible performance on a play that shifts the dynamic of a game in favor of the player's team. On the other hand, a −2 is a play that catastrophically hinders a team's chance of winning, such as a quarterback throwing a pick-six in the fourth quarter of a close game. Ambiguous plays where the outcome is unclear on how a player impacted their team are typically given a 0. The sum of these plus-minuses are then converted on a 0–100 scale and produce a grade for a single game. However, a player's season grade is not the average of the 17 grades a player receives each game. Instead, PFF credits a player's entire body of work and longevity throughout the season. It is, therefore, possible for a player to have a higher season grade than any individual grade that a player received in any game he played in. ==Records==
