With a stable full of senior receivers in this draft, Harper needed to post career-highs in 2007 to prove he wasn't just a size/speed candidate for the NFL -- and that is precisely what he did - emerging as the Hokies' most dependable downfield target. Unfortunately, scouts will have to determine who is the real Justin Harper -- the mercurial wideout who struggled to make an impact throughout his early career despite obvious physical tools, or the one who stepped up his play as a senior.

Positives: Rare height for the position … Lean build that could handle an additional 10 pounds of added muscle without a significant loss of speed … Elite timed speed … Supposedly timed at a 4.33 by Virginia Tech coaches during the spring -- fastest on the team … Uses his size and leaping ability to make the tough, acrobatic catches against tight coverage … Generally reliable hands.

Negatives: More style than substance throughout most of his career … Tall, but lacks the thick, strong build to handle when cornerbacks press him … Elite straight-line speed doesn't translate well on the field due to his long-stride running style … Marginal quickness out of his breaks … Lets too many passes get into his pads, resulting in some ugly drops … Limited production until his senior season.
