If every decent Australian League player swapped codes NZ and the rest would be fighting for 2nd place

Could equally say that if the decent All Blacks swapped, the Kiwis would push the Kangaroos hard - again pointless...
The best young athletes in NZ generally play union, unfortunately - and union is second (or 4th?) rate in Aust...
Dave Taylor would be ordinary in union, as would many league players (he could be the equivalent of Garrick Morgan, just ill-suited to the change)... and we know many union player have been ordinary in league (the exceptions generally being the truly excellent union players that swapped - e.g., Innes, O'Connor, Tuigamala, Papworth (if he wasn't glass) and Ridge)
