There are a few exceptions as each position group has different rules, but those are the basics. THE GRADING SCALEĮach player is given a grade of -2 to +2 in 0.5 increments on a given play with 0 generally being the average or “expected” grade. This style has worked well in unlocking undervalued gems through the years, while also not being swayed by player hype if it is undeserved. Preconceived level of ability has no impact on the grading system. We also work to eliminate bias by not caring about the level of player who is being graded, so whether it’s the best tackle in the league missing a block or one of the worst, the same grade is given. Taking every play into consideration allows for a larger sample size of data to tell the proper story rather than just a highlight reel of plays that we tend to remember, for better or worse. The benefits of this style of grading are numerous. The grading system was founded on the principle of grading “production” rather than traits or measurables, but perhaps a better way to describe it is a player’s “contribution to production” on a given play.ĭid the quarterback make a great throw, but it was dropped? The quarterback contributed to positive production and will receive a positive grade for that effort, even though the receiver let him down, earning a negative grade along the way.
