Between Fiji, Samoa, Tonga, who do you reckon is: The Best Rugby Union Nation The Best Rugby League Nation The polynesians are some of the best natural athletes in the world and with rugby as their national sport so many of them have achieved a lot in rugby. They're big, skillful and fast - the perfect build for rugby. I think Fiji is the best at rugby union - they've produced so many good players and are the best athletes in the world imo - they're athletic ability is scary. Two QF berths and a number of them have played for the AB's and Wallabies, followed by Samoa, then Tonga. imo its vice versa in league. Tongas the best, then Samoa then Fiji - they'res so many Tongans and Samoans in the NRL especially, they're fantastic to watch. Thoughts.
