Superman Does Jumping Jacks. Okay, Now Stop Doing That. Thank You.
See, this is what a "superhuman" does. Jumping jacks at a Redskins rah-rah draft day "pep rally" just a few months after his multiple ligament reconstructive surgery. He says he'll be ready by Week 1. And I believe him. However, I hope he keeps stuff like this to a minimum for at least a while.
Because I remember Arizona kicker Bill Grammatica blowing out his knee just celebrating a made field goal.
