![]() ![]() PFF grades the play, not its result, so the quarterback that throws the ball to defenders will be downgraded whether the defender catches the ball to notch the interception on the stat sheet or not. ![]() Conversely, they can dump the ball off on a sequence of screen passes and end up with a gaudy looking stat line if those skill position players do enough work after the catch. Quarterbacks can throw the ball straight to defenders but if the ball is dropped, you won’t see it on the stat sheet. Statistics can be indicative of performance but don’t tell the whole story and can often lie badly. We aren’t grading players based on the yardage they rack up or the stats they collect. Their explanation of their PFF score versus game stats is explained as follows: One thing which PFF does in its rankings is looks at every play a player is on the field and not just the “splash plays” which can lead to a great statistical performance. Just because a player was quiet during the game does not mean he played poorly, and in certain positions it could mean he played very well, but had little to feature on the highlight reel. ![]() Was he gaining a slight edge every one of those snaps, or was he struggling just to maintain parity?īy recording performance on every single snap, we come to a more complete conclusion and evaluation. Our rankings are more of a performance evaluation, and a reflection of how efficiently a player made plays in the time he was on the field.Īnother key benefit to PFF’s grading system is building a complete picture of a player’s performance.Įven watching a game closely can result in something of a mental highlight reel on a player – remembering the few good and bad plays and making an overall judgement based on the balance of those – but it can be the other 40 snaps in the game that are being ignored that held the true key to his performance. We are not necessarily telling you who the best players are. ![]() Talented players can have bad games, runs, or even seasons, and often players without nearly as much talent can put together impressive play on the field. It’s important to understand that PFF is not grading talent in these numbers, rather strictly performance on the field. Similarly, playing badly for a long time is a greater problem than playing badly once, so the grade can also be compounded negatively. It is entirely possible that a player will have a season grade higher than any individual single-game grade he achieved, because playing well for an extended period of time is harder to do than for a short period. Achieving a grade of 90.0 in a game once is impressive, doing it 16 times in a row is more impressive. Season-level grades aren’t simply an average of every game-grade a player compiles over a season, but rather factor in the duration at which a player performed at that level. They are finally converted to a 0-100 scale and appear in our Player Grades tool. These grades are verified by the Pro Coach Network, a group of former and current NFL coaches with over 700 combined years of NFL coaching experience, to get them as accurate as they can be.įrom there, the grades are normalized to better account for game situation this ranges from where a player lined up to the dropback depth of the quarterback or the length of time he had the ball in his hand and everything in between. On every play, a PFF analyst will grade each player on a scale of -2 to +2 according to what he did on the play.Īt one end of the scale you have a catastrophic game-ending interception or pick-six from a quarterback, and at the other a perfect deep bomb into a tight window in a critical game situation, with the middle of that scale being 0-graded, or ‘expected’ plays that are neither positive nor negative.Įach game is also graded by a second PFF analyst independent of the first, and those grades are compared by a third, Senior Analyst, who rules on any differences between the two. According to their website pff.com they give following explanation as to how they determine their grades: The first thing which is needed is to understand how PFF breaks down each player in order to come up with an overall score. So how much can fans truly trust these grades? There are many fans who swear by the rankings while others dismiss them completely. With many of these positions, many often turn to the Pro Football Focus (PFF) player grades they issue for the season. While some positions have much easier data to compare, others are very difficult to quantify with statistics. As the NFL offseason presses on, fans are evaluating how players from their favorite team performed in 2019 in order to determine how they view the position going into both free agency and the draft. ![]()
