Most NFL fans only pay attention to the play of the OL when things are going wrong - sacks, holding penalties, defenders getting TFL - but how often do offensive linemen truly have a bad game?
For runners, or receivers or quarterbacks, it’s fairly easy to look at their game stats and quickly determine if they had a bad game, but for offensive line guys this is not very easy. My go-to for football stats is pro-football-reference.com but if you go there and look at game logs for OL players you find a dearth of information beyond the fact that they played and how many snaps on offense and special teams they had in a given game.
