Pro Football Focus (PFF) has become a prominent source for evaluating player performance in both the NFL and college football. But what exactly is Pro Football Focus, and how does their grading system work? This article dives deep into the methodology behind PFF, explaining how they evaluate players, the grading scale they use, and how the data can be used to gain unique insights into the game. If you are looking for trusted and easy-to-understand answers, CAUHOI2025.UK.COM offers comprehensive explanations on various topics. Explore player grades, advanced statistics, and in-depth football analysis.
1. Understanding Pro Football Focus (PFF)
Pro Football Focus (PFF) is a sports analytics company that provides in-depth data and analysis on player performance in American football. Unlike traditional statistics, PFF focuses on evaluating individual player performance on every single play of every game. This detailed approach offers insights that go beyond the box score, providing a more comprehensive understanding of a player’s contribution to their team.
PFF’s grading system is built on the principle of evaluating a player’s “contribution to production” on each play. This means that analysts assess what a player is supposed to do and how well they execute their assignment, regardless of the play’s final outcome. For example, if a quarterback makes a perfect throw that is dropped by a receiver, the quarterback will still receive a positive grade for their contribution, while the receiver will receive a negative grade.
2. The PFF Grading System: A Detailed Look
The PFF grading system assigns a grade from -2 to +2, in 0.5 increments, to each player on every play. A grade of 0 represents the average or “expected” performance. This scale allows analysts to differentiate between exceptional plays, poor performances, and everything in between.
- +2: Represents an exceptional play, such as a perfect deep pass or a game-saving tackle.
- +1 to +1.5: Indicates a very good play, exceeding expectations.
- +0.5: Shows a slightly above-average play.
- 0: Denotes an average or expected play.
- -0.5: Indicates a slightly below-average play.
- -1 to -1.5: Signifies a poor play, falling short of expectations.
- -2: Represents a disastrous play, such as a game-ending interception or a missed assignment leading to a significant loss.
Each position has its own grading rubric that considers the specific responsibilities and expectations for that position.
3. Eliminating Bias and Focusing on Contribution
One of the key strengths of the PFF grading system is its effort to eliminate bias. Graders focus solely on the player’s execution of their assignment, regardless of their reputation or perceived skill level. This approach helps to identify undervalued players who may be performing at a high level despite not receiving widespread recognition.
According to PFF, preconceived level of ability has no impact on the grading system. This allows them to uncover undervalued players and avoid being swayed by hype if it’s undeserved.
4. Adjustments for Context
Raw grades are adjusted to account for the context of each play. This involves considering factors such as the game situation, the opponent, and the player’s role within the play. For instance, a player’s grade might be adjusted slightly downward if they play in a historically more favorable situation, while a player in more unfavorable circumstances might receive an upward adjustment.
PFF collects over 200 data points on each play to determine the baseline or expectation for each player. This data-driven approach ensures that grades are fair and accurate, reflecting the true contribution of each player.
5. Facets of Play: Breaking Down Performance
PFF breaks down player performance into specific “facets” of play. These facets include:
- Passing: Evaluating a quarterback’s accuracy, decision-making, and ability to make throws under pressure.
- Rushing: Assessing a running back’s ability to gain yards, break tackles, and protect the ball.
- Receiving: Evaluating a receiver’s ability to catch passes, gain yards after the catch, and create separation from defenders.
- Pass Blocking: Assessing an offensive lineman’s ability to protect the quarterback from pressure.
- Run Blocking: Evaluating an offensive lineman’s ability to create running lanes for the running back.
- Pass Rushing: Assessing a defensive player’s ability to pressure the quarterback.
- Run Defense: Evaluating a defensive player’s ability to stop the run.
- Coverage: Assessing a defensive back’s ability to cover receivers and prevent completions.
- Special Teams: Evaluating performance in kicking, punting, returning, and general special teams play.
By evaluating these facets, PFF provides a comprehensive view of a player’s strengths and weaknesses.
6. Who are the PFF Graders?
PFF employs a large team of analysts who meticulously review game footage and assign grades. Less than 10% of PFF analysts are trained to the level where they can grade plays. Only the top 2-3% are senior analysts in charge of finalizing each grade after review. These graders undergo months or even years of training to master the PFF grading process, which includes a 300-page training manual and video playbook. The team includes former players, coaches, and scouts.
PFF Grading
Each grade is reviewed at least once, and usually multiple times, using every available camera angle, including All-22 coaches’ tape. This thorough review process helps to ensure the accuracy and consistency of the grades.
7. Addressing the “You Don’t Know the Play Call” Critique
One common criticism of PFF is that graders cannot know the specific play call and therefore cannot accurately assess a player’s assignment. PFF addresses this concern by stating that they grade what a player attempts to do on a given play. While nuances exist in football regarding preparation and adjustments, once the ball is snapped, most players’ objectives are clear, and PFF evaluates accordingly.
In cases where there is ambiguity about a player’s assignment, PFF can defer to a “0” grade to avoid guessing. These situations are rare, and PFF believes that missing a handful of these plays throughout the year does not significantly affect player evaluations.
8. Converting Grades to a 0-100 Scale
The plus-minus grades are converted to a 0-100 scale at the game and season level. This conversion makes it easier to compare players across positions, although it does not account for positional value.
It’s important to understand that season-level grades aren’t simply an average of every game-grade a player compiles over a season, as the season grade credits the entire body of work.
9. Grades vs. Stats: Understanding the Difference
It is important to differentiate PFF grades from traditional statistics. PFF does not grade players based on the yardage they accumulate or the stats they collect. Statistics can be indicative of performance, but they don’t always tell the whole story.
For example, a quarterback might throw the ball directly to a defender, but if the ball is dropped, it won’t show up on the stat sheet. Conversely, a quarterback might dump the ball off on a series of screen passes and end up with impressive passing stats if the receivers gain significant yardage after the catch.
PFF grades the play, not its result.
9.1 Vic Beasley Example
Vic Beasley’s 2016 season provides a great example of the difference between grades and stats. Beasley led the NFL in sacks but was only the 31st-ranked edge rusher in terms of PFF pass-rushing grade. This discrepancy was due to several factors:
- Not all sacks are created equal: Many of Beasley’s sacks were unblocked or cleanup sacks that owed more to other players than to his own skill.
- Pressures matter: PFF considers all pressures, not just sacks. While Beasley led the league in sacks, he was only 18th in total pressures.
- Run defense matters: Beasley was not as strong in run defense, which is also factored into PFF grades.
According to an analysis by Pro Football Focus, sacks are worth around 2.1 pressures of any other kind.
10. Using PFF Data for Player Evaluation
PFF grades provide a valuable tool for evaluating player performance, but they should be used in conjunction with other data and context. Factors such as a player’s role within the team, the quality of their competition, and their overall skillset should all be considered.
PFF+ allows users to sort by player grades and access advanced stats that provide additional context. This combination of grades and data provides a comprehensive view of a player’s performance.
PFF grading is not perfect, but it is a unique look at a player’s production, and when paired with PFF’s advanced data, it’s one of the most powerful tools in the game. PFF grading is both descriptive and predictive, and in many cases, we’ve debunked myths about traditional stats, showing that the production grade is a better indicator of what happened on the field and what will happen going forward.
