You could make an argument against the Indianapolis Colts’ offensive line as the most improved unit in football this season, but you better be pretty good at arguing. Indianapolis ranks 12th in offensive DVOA, 10th in yards per drive, and sixth in points per drive. Much of that success can be pinned on the big guys up front.
The easy thing to say is how big a deal the addition of Quenton Nelson, the sixth overall pick in the 2018 NFL Draft, has been. That is true, but not nearly the whole story.
