With training camp beginning and another NFL season on the horizon, Detroit Lions head coach Dan Campbell had to prove he's still in elite shape.
As many people know, the Lions' leader was a tight end in the NFL not too long ago and played 10 seasons and 114 games. If you didn't know any better, you might think Campbell could still get a few snaps with the guys.
Campbell, who turned 47 in April, is still a workout fanatic and brings all kinds of energy to every practice, which is one of the things his players love about him.
