[post_page_title]Do a barrel roll[/post_page_title]
What is this guy doing? It looks like he is doing a flip over the ball, about to land on his feet, and then throw the ball back in bounds in order to re-start the play of the game. Is that even legal? Maybe this guy simply has really good balance and core strength, and is just showing off for people who are located just off camera. In any case, this guy clearly has some athletic abilities. Maybe he should take the field.
