INDIANAPOLIS - Terron Armstead is ridiculously fast for a big man.

On Saturday morning, the 6-foot-5, 306-pound offensive tackle had everybody at the NFL scouting combine buzzing, after he ran the 40-yard dash in 4.65 seconds.

The University of Arkansas (Pine Bluff) product's official time was later downgraded to 4.71 seconds, after his second of two runs. But still.

How fleet is that for an offensive lineman?

Hall of Fame wide receiver Jerry Rice ran the 40 in 4.65 seconds at the NFL scouting combine in 1985. Yeah, same time as Armstead's unofficial first attempt.
