A couple of years ago I started looking at ways to measure the overall health of a team’s offensive line during a season. I started by using games started, but that led to some confounding results. So I have moved to using snap percentage.
Starting offensive lineman generally play every offensive snap if they are healthy. The only other position on offense that can say that is quarterback. So using snap percentage (player snaps/total team snaps) to track league-wide offensive line health is a viable method.
The Denver Broncos OL was quite healthy in 2024, but in 2022 and 2021 the OL was one of the least heathy OL’s in the league.
