South Carolina's Jadeveon Clowney is the top defensive end prospect in the 2014 NFL Draft. He opened some eyes at the NFL Combine by registering a 4.47 in his first unofficial attempt at the 40-yard dash on Monday.
266-pound Clowney's unofficial 4.47 40 would've finished sixth among this year's *running backs*.

Clowney's unofficial 40 time is faster than every active QB that has ran at the combine since 2006 except Robert Griffin III.

According to NBC Sports, Clowney's official time in the 40-yard dash is 4.53 seconds.
To get a good idea of just how fast this time is for a 6-foot-6, 250-pound defensive end, this GIF illustrates Clowney running alongside lightning-fast Oregon running back DeAnthony Thomas, who logged an unofficial 4.34 at the Combine.
