University of South Carolina star, and number one draft pick, Jadeveon Clowney stopped by The Tonight Show on the eve of the 2014 NFL Draft to have a chat with Jimmy Fallon. After a chat about Clowney's impending future millions and his more-than-likely new home in Huston with The Texans, Fallon decided to see if he could get anywhere near Clowney's 4.53-second 40-yard dash from the NFL Combine. 

Check out the clip below and tune into the draft tonight on ESPN from 8:00pm-11:30pm.
