There might not be a running back in the nation with Harper’s skill set. He is too quick and elusive to be considered a power back, but that is his style of play. He is very physical, playing behind his pads with textbook precision. He will hit most holes with low, square pad level and deliver the blow as he falls forward. He will pick up the tough yards.

At almost 220 pounds, Harper shows the ability to maneuver in small spaces, run away from defenders and impact the passing game in a way no power back can. He is surprisingly light on his feet and shows remarkable quickness in the open field for a prospect of his size. Harper is the most polished pass catcher from the pure running back position. 

Oregon’s Jonathan Stewart is a solid comparison. Harper’s one area of weakness is his top-end speed. Stewart returns kicks for the Ducks; Harper does not have burner speed like that. Otherwise, Harper is a four-down running back and will be used in 3rd-and-long, as well as along the goal line.
Harper is an outstanding prospect and has NFL stamped on his forehead.
