That backline would have eleventybillion points put on it too
So we'd be winning games twentybillion points to eleventybillion points. Who'd complain.
It takes those world class spinters 0.15 of a second to react and within 2 seconds they are doing over 36 kph.
Asafa Powell would generate more leg drive than 3 billy slaters.
If a fullback ever comes a long with close to the athletic ability and raw power that a world class sprinter has then he would be toying with chasers and averaging 50 metres per kick return unless they committed a 7 or 8 man kick chase everytime.
To be honest, American football has always possessed athletes that could also be world class sprinters if they wanted. So it's possible the NRL might have a couple one day. Hayne is as close as we have, he has a sprinters build and if he went down that path he probably could have made world meets.
