Joseph Ferraiola, who has previously worked with an MLB club, Next Gen Stats and a management firm that represented both players and coaches, recently published some interesting data on what NFL receivers’ “real” 40-yard dash times are based on player tracking data. I’m sure you’ve heard that a player’s 40-yard time doesn’t match their “on-field” speed at some point while following football. Farraiola’s new model attempts to actually quantify that “on-field” speed for comparison.
Obviously, it’s not normal for receivers to start out plays in a three-point stance without any sort of football gear, as they do when they’re running their 40-yard dashes at the combine.
