In case you missed it, Jadeveon Clowney absolutely crushed his 40-yard dash at the NFL Combine earlier today – running an unofficial 4.47 and 4.48 in his two attempts. Like the rest of us, Warren Sapp was pretty blown away (evidenced by the GIF above) while watching the South Carolina defensive end sprint down the field. He actually looks quite terrified by Clowney’s athleticism, and I can’t say I blame him.
