FP/snap
“FP/Snap” in American football often means “Fantasy Points per Snap.” Fantasy Points are the metrics employed in fantasy football, in which players create fictitious teams out of actual NFL players and get points depending on how well those players perform in actual contests.
The term “snap” here refers to how frequently a player is involved in an offensive or defensive play. In other words, it refers to how many plays a player participates in throughout a game.
Therefore, “FP/Snap” is a measure that determines the average number of fantasy points a player scores for each play they are in the game. It’s a means to assess a player’s effectiveness and production on a per-play basis, which fantasy football players may use to evaluate players’ prospective worth and decide who to include on their squad.
