With the 2013 NFL combine underway, it hasn't taken long for a handful of high-end prospects to separate themselves from the pack with standout performances in physical testing.
Specifically, the 40-yard dash has a history of highlighting and singling out potential top-10 picks, as the fastest players are obviously hot commodities among NFL scouts.
For example, after recording the fastest 40 time at the 2009 combine, Darrius Heyward-Bey was taken by the Oakland Raiders surprisingly early. Al Davis' squad snatched up the speedy receiver with the No. 7 pick in the draft.
Now, with just three days to go in this year's combine, here's an early look at some of the fleet-footed prospects who have boosted their stocks with solid performances in Indianapolis.

Coming out of Arkansas-Pine Bluff, it's not a surprise that Terron Armstead is CBS Sports' No. 10 offensive tackle heading into the draft. Unfortunately, that's simply what happens when a player is entering the draft after emerging from a rather unheralded program.
But so far, Armstead has been a monster at testing. He tested as one of the best at his position at both the broad and vertical jumps, and he posted the best time among all offensive tackles in the 40, clocking in at a blazing 4.71.
Armstead might be a project at this stage, but given his speed and athleticism, there's no doubt he has the physical gifts to play in the NFL.
Until the wide receivers check in for the 40, former Arkansas Razorback Chris Gragg will be the top dog in the 40, as the tight end registered an impressive time of 4.50 at the combine.
In addition to his speed, Gragg has recorded high-end numbers in both the broad and vertical jumps. And with his strength and speed, some scouts may overlook his history of injuries.
He won't be among the first tight ends taken in April, but if his results at the physical testing portion of the combine are any indication, Gragg merits a second look from teams in need of a blocking tight end.
Heading into the combine, CBS Sports had former Maryland Terrapin Matt Furstenburg so low on its tight end rankings that the New Jersey native projected to go undrafted at April's NFL draft.
But despite flying under the radar after hauling in 206 yards and two touchdowns as a senior, Furstenburg has impressed at the combine, posting one of the best 40 times among all players thus far.
With a time of 4.62, the All-ACC tight end could hear his name called during the later rounds of the draft. And in the right situation, he could materialize into a second-day steal.
