Freddie Flintoff
NFL players are rarely successful when they turn to combat sports. But it’s not too surprising to see them take this step because of football’s physicality. However, cricket is a different story because there is no contact at all. Britain’s Flintoff surprised many people when he announced his professional boxing debut.

This became one of those freak shows that blew up because of his relative celebrity profile. He defeated Richard Dawson on points after a tough battle. Flintoff revealed his limitations in the bout but he enjoyed the experience. He also fought in front of a full venue because of his popularity (via TalkSport).
