Day 3 of the NFL Scouting Combine saw really big men running in spandex. Yes, the offensive linemen were on full display and, for the most part, were surprisingly fast. 

One guy was so fast that he actually broke the record for the 40-yard dash by an O-lineman. Arkansas-Pine Bluff tackle Terron Armstead got NFL front offices buzzing with his record-setting 4.65 in the 40. 

Will his stock rise just because of his 40? Well, it sure can't hurt. Check out the video above for more stock reports from the NFL Scouting Combine.
