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.
