‘This sport is crazy’: American football legend loses it over ‘nuts’ NRL video

Reggie Bush knows a thing or two about running hard.

He ran for 5,490 yards in his career as an NFL running back, tasting Super Bowl success with the New Orleans Saints in 2010.

Even still, that seemingly does not compare to what NRL and NRLW players put themselves through every week they take to the field.

It may be the rugby league off-season but there is little doubting the game has grown in popularity after a tweet from Bush on Friday.
