According to Pro Football Focus’ Seth Galina (subscription), new Indianapolis Colts starting veteran quarterback Philip Rivers should really benefit passing behind an improved offensive line—especially over the porous one he threw behind in 2019 with the Los Angeles Chargers:
Of the 224 offensive linemen who played at least 100 snaps in the 2019 regular season, three of the bottom 25 in individual pass-blocking efficiency were Chargers. Of the 136 offensive linemen who played at least 400 snaps, the Chargers had two in the bottom five.
