Brandon Thorn and his Trench Warfare Substack have been analyzing and ranking offensive and defensive linemen performances for almost a decade. His approach is based on film study and grading players on a scale from one to seven, as NFL teams would in their scouting reports for college and pro personnel. He recently released his top 15 at each of the five OL positions, and Pittsburgh Steelers LG Isaac Seumalo was the lone Steeler on the list. He was eighth of the 15 left guards that he ranked and placed in the third tier of “good or above average” players.
