The true measure of a pro prospect is in his tape, but historically we've seen "workout warriors" get tremendous boosts in their NFL draft stock, especially if it matches up with what we see on tape.
Combine numbers typically serve as quantifiable confirmation of a player's physical attributes, from height and weight to speed and explosiveness. These attributes can often make or break a kid's draft stock. With this in mind, it's fair to say a ton of money is either earned or lost during these critical days in late February.
With a few blazing times or amazing jumps, yesterday's nobody can quickly become a prospect on everybody's radar, as he likely will be soaring up draft boards in the weeks that follow. This slideshow takes us on a journey to uncover which prospects are doing just that now that combine results are officially in the books.
Note: Throughout the article, I frequently reference a DMR grade, or measurable grade; you can read a full description of how that grading system works as I described it in a previous article. You can also see the complete DMR results from last year in my Google doc. The 2013 DMR results will be made public and kept up to date within a week or so.
