Alabama wide receiver Amari Cooper ran a blazing 40-yard dash with an official time of 4.42 seconds on Saturday at the NFL Scouting Combine. Cooper's second attempt was the seventh-fastest 40 time by a wide receiver in Indianapolis.

But the former Crimson Tide receiver's biggest competition ahead of the 2015 NFL Draft, West Virginia wide out Kevin White, ran a faster time, being officially clocked at 4.35 seconds in the 40 for the third-fastest time by a receiver.

However, the NFL Network produced a simulcast video of Cooper, White and Louisville wide out DeVante Parker, who ran a time of 4.45 seconds, running the 40 at the same time. Check out the video below:

Rich Eisen and Mike Mayock of the NFL Network are speaking during the video, and Eisen labels the receivers in order from first to last as Parker, White and Cooper. But that appears to be incorrect, as the receiver pulling up the rear in the simulcast is wearing a No. 35 shirt. Cooper was the No. 9 receiver at the NFL Combine. Parker was No. 35, while White was No. 43. Those shirt numbers are based off the alphabetical order of the players' last names.

So, by looking at the video, it appears that Cooper, who beat White across the line by a couple of feet, ran the fastest 40 time of the top-three wide receiver prospects at the NFL Combine on Saturday in Lucas Oil Stadium.
