There is no real equivalent such was the impact Jonah Lomu made on the game of rugby. The closest would be Messi or Ronaldo but they are a long way short (if you excuse the pun).
Pele would probably be a good equivalent as he was the first big global superstar in that sport.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
