Sacks allowed by the lineSacks per dropback, leaving out those FTN charted as the quarterback's fault (holding the ball, running into the rush). FTN charting, 2023 on.

The line's rate while he was on the field, credited by his share of snaps: public data doesn't say which blocker allowed a sack or opened a hole.	Yards before contact per carryHow far runners got before first being touched (Pro Football Reference, 2018 on), the clearest sign of run blocking.

Pressure rate on his snapsDropbacks where the quarterback was pressured or sacked, counted over the plays he was actually on the field (nflverse participation, 2016 on; published after each season, so not yet for the current one). Still the whole line's result: public data doesn't say which blocker was beaten. Rates before 2023 run a few points higher, from a change in the source's charting.	Pressure rate vs 4 or fewer rushersPressure rate on his snaps when the defense rushed four or fewer, so no extra blitzers to pick up: the purest public measure of a line's protection (nflverse participation, 2016 on; published after each season).	Sack rate on his snapsSacks per dropback over the plays he was actually on the field (nflverse participation, 2016 on; published after each season). Still the whole line's result.
