That's Ole Miss wide receiver Laquon Treadwell running. This is what athletes do normally and without much fanfare, but Laquon Treadwell is the guy you last remember running towards the endzone for a game-winning TD against Auburn on November 1st before...well, before he was tackled from behind, suffered a horrendous leg injury, fumbled the ball as a result of the pain, and played a brutal role in the worst ending to a football game we've ever seen. So this is running, sure. It's also a fantastic sight to see just four and a half months after utter disaster.
(P.S. That's Denzel Nkemdiche running next to him. He is not a slow man.)
