The advanced metrics for the Western Michigan offensive had them as one of the best offensive lines in the nation. The run blocking yielded yards and running lanes and the pass blocking gave Eleby time to find receivers— often an excess of time.
My favorite ways to measure an offensive line are stuff rate, line yards and front seven havoc rate. Stuff rate is the percentage of plays that are stopped at the line of scrimmage or behind. Line yards is a weighted formula where the line gets credit or blame for certain distances of yardage gained during a run play.
