Former Oklahoma State cornerback Justin Gilbert is trying to be the first defensive back taken in the 2014 NFL draft, and he was able to help himself out at the combine after showing off his speed in the 40-yard dash.
You can see a GIF of his 40-yard dash below.
Gilbert clocked in at an official time of 4.37 seconds, which was one of the fastest time among defensive backs.
Bleacher Report's own Matt Miller had Gilbert as his top cornerback and No. 10 overall player on his pre-combine big board.
