14. Bismarck Du Plessis
A name that won’t be familiar to most U.S. sports fans, Du Plessis is a South African rugby player who plies his trade in France. He plays for Montpellier who is also one of the best teams in their league. However, rugby players – like American football stars – have a lot of testosterone and this sometimes erupts. But when it does, it gets a little bit terrifying.

Montpellier was warming up for their game against arch-rivals Racing 92 when somebody said something and Du Plessis erupted. He got physical as he launched a punch at a teammate before other players quickly dragged him away. If their plan was to intimidate Racing 92 with their savagery, it worked because they won 41-3.
