I wouldn't rid the competition of its foundations, soul or credibility. My version of the comp would keep all of the clubs that ensure that: Brisbane, Melbourne, Warriors, Eels, Souths, Dogs, Roosters, Dragons. Other clubs are free to apply but not all will be successful.
All others that didn't make my NRL would be looked after with the respect that they deserve, in a national fully professional second teir that is televised and that is not just relegated to being full of feeder clubs to the NRL. My second teir would add even more traditional rivalries to the game of RL than the NRL can hold alone and will be more affordable to run than the NRL allowing clubs to play at traditional suburban grounds against traditional suburban rivals in family friendly time slots.
