Line Analytics
How each offense runs the ball and protects the passer, against the league: yards per carry and success rate by run direction, and sacks, QB hits and hurries allowed per dropback, for every NFL and FBS team this season.
About these numbers
- Where does the data come from?
- NFL: the league play-by-play published by nflverse (nflfastR), FTN charting to leave screens and trick plays out of pass protection, and ESPN depth charts for the starting five. College: ESPN play-by-play for every FBS game. It refreshes every few hours during the season.
- What is a successful run?
- A run that gains 40% of the yards to go on 1st down, 60% on 2nd down, or all of them on 3rd and 4th down. Success rate is successful runs divided by the runs that could be judged. The Method button on the dashboard lets you change the rule.
- Why run direction and not gaps?
- Official play-by-play records where a run went (left end, left tackle, left guard, up the middle and the same on the right for the NFL; left, middle or right in college), not the gap it hit. The chart places each direction over the lineman it names.
- What counts as pressure?
- For the NFL, sacks and QB hits, per 100 dropbacks. For college, sacks and the hurries stat crews note. Public data does not say which blocker allowed a pressure or where the rush came through; the dashboard can import charted data that does.
