Focus released their rankings of each offensive line unit in the NFL up to this point in the season Wednesday. The rankings seem to be based on their popular player grades they release after every game.

According to the PFF grades, right tackle Rick Wagner is the best of the Lions offensive lineman. He has earned a 76.7 through five games this season.

Both Ragnow and left tackle Taylor Decker were first-round picks. Wagner and guard T.J. Lang were big money free agents the Lions snagged in the spring of 2017 and center Graham Glasgow was a Day 2 draft selection. Every single one of them was a player brought in by Quinn and the new-and-improved unit seems to have lived up to his expectations.
