i think it needs to go to a 14 team comp with every team playing each other twice have the comp divided up into 2 leagues (7 in each league)
top 2 from each league go through to the finals and the best 2 records in the nrl other then the top 2 from each league go through to the finals aswell.
the way the leagues are determined is by where you finish on the ladder ie (teams that finish 1,3,5,7,9,11,13 are in league 1 teams that finish 2,4,6,8,10,12,14 are in league 2)

16 teams
4 divisions with 4 teams in each
division 1\. Broncos, titans,cowboys, storm
division 2\. warriors, knights, raiders, sharks
division 3\. sea eagles, eels, panthers bulldogs
division 4 Rabbitohs, roosters, dragons,tigers
21 round season
every team in the division plays other teams in the division 3 times and every other team ounce
top team in each division get in the finals
