The 40-yard dash at the NFL Combine is just a strange event. It basically has little to no bearing on your NFL career as long as you stay within the expectations that come with your position. However, a substantial difference in time in either direction—whether that be faster and slower—can greatly impact your draft stock. With that being said, the drill matters… and doesn’t matter at the same. 

For some athletes, one slip-up of just a couple seconds in their 40-yard dash time can cost them a higher spot in the draft and millions of dollars or even worse, a potential spot on an NFL roster. From those prospects, like Tom Brady and Antonio Brown, who have experienced potentially detrimental failures while running the 40 only to come out better once they got their chance and entered the league to the players who weren’t as lucky and allowed one bad run to dictate their entire future in the NFL Draft, the 40 has proven to be a double-edged sword.

Instead of focusing on the athletes who blew away their field with an impressive showing of speed, we’re going to take a look at the worst of times for these NFL prospects. The ones who took part in the 40 only to wind up regretting their decision on the end.

Here’s a roundup of the most embarrassing 40-yard dashes in NFL Combine history, for your sadistic viewing pleasure.
