Note: This is the second of four offseason snapshots looking at the peaks and valleys of key 2017 Vikings contributors. Part I: Harrison Smith. Dalvin Cook’s first and 74th carries, unfairly ominous bookends to his NFL rookie season, might have been the same play. With two tight ends tucked closely to the left tackle, a weakside handoff and inside zone run awaited Cook on each snap. The results, one yard against the Saints and 10 yards through the Lions, showed an heir and offensive line quickly outgrowing Adrian Peterson’s shadow. Still the potential was greater for each play, the first a resounding dud and the last a season-ending torn ligament in Cook’s left knee. Cook started to reward the Vikings for trading up to make a second-round pick of the Florida State star nearly one year ago.
