So as aging offensive lineman, I can tell you that the offensive line only gets noticed when they do something wrong - false start, holding, ineligible downfield, or allow a sack. All of these things will get you singled out when you are used to toiling in relative obscurity. In my article earlier this year, I reviewed the performance of the offensive line overall.
In that piece, I shared the data from Stats Inc regarding how many sacks each of the offensive lineman was responsible for during the 2018 regular season. I don’t trust their sack blame assessment, so I have undertaken to do my own (as I have done in previous years).
