NATE EBNER ARMAND DUPLANTIS
US, Sevens rugby
The three-time Super Bowl winner with the New England Patriots has returned from the NFL to try to regain the US Sevens berth he held in Rio.
Played rugby as a junior in Ohio and for US underage teams and has maintained a deep-seated love of the sport despite being lured by the bright lights of the NFL.
He is one of 30 players trying out for 12 spots in the US team and said winning an Olympic gold was a major sporting priority.
Tipped by scribes to be one of the superstars of the Games, he is a pole vaulting phenomenon who has soared to great heights.
The son of a pole vaulter and raised in the United States as the son of an American father and Swedish mother, he first tried the sport at age three and held his first world record four years later.
Now he has left giants such as Sergey Bubka in his wake by posting indoor and outdoor world records.
