Alabama defensive lineman Quinnen Williams is a big man. He measured in at 6-foot-3, 303 pounds at the 2019 NFL combine. And yet, he can really move. That was put in evidence by his 40-yard dash time of 4.87 seconds during the athletic testing portion of the combine. 

Damn, look at that speed! 

Naturally, after Williams blew away the competition at defensive line with his first time, his agent, Nicole Lynn, advised him not to bother running a second time. After all, what are the odds Williams would improve on such a good score for such a big man? Well, maybe those odds weren't great, but let Lynn tell the story of what happened. 

That's right. Williams did even better the second time around, running the 40 in an unofficial 4.84 seconds, which was later corrected to 4.83 seconds. 

Williams is considered a potential top-5 pick in the draft coming off a season where he finished with 91 tackles including 19.5 for loss, as well as eight sacks. He's possibly the best interior defensive lineman available, and after a strong day of testing should join Nick Bosa and Josh Allen among the small handful of top overall prospects.
