6. Julio César la Cruz (Light heavyweight boxer, Cuba)
Cuban boxers have won 32 gold medals over the years, and the fighter most likely to add to that total this summer is light heavyweight Julio César la Cruz. A product of boxing hotbed Camagüey, César la Cruz won gold medals at the 2011 World Amateur Boxing Championships in Baku and the 2011 Pan American Games and, as evidenced in the clip above, comes into London with the backing of a highly enthusiastic fanbase.
