sacks from CFBD play-by-play; college has no charted pressure, and these rates are not opponent-adjusted Measured on 7,926 team-games 2022–25: a college line's sacks-allowed rate carries +0.27 into its next game and a defence's sack rate only +0.10 — the line is most of this. The pairing predicts the game's sack rate +0.27, yards per dropback −0.16 and points added per play −0.15. Heaviest quarter of pairings against lightest: 7.8% vs 4.2% sack rate, 6.1 vs 7.2 yards per dropback.

Rank gap = the defence's FBS rank minus the offence's on the same measure: +60 means the offence ranks 60 places better than the defence it faces. Unit against unit only — college has no player charting to name a matchup by.
