Conferences could be used to emphasise rivalries, but there is no need for distinct, separate conferences or divisions until the comp grows to at least 24 teams. Even at 22, you could still have a good comp where you play every team once + your 3 biggest rivals twice.
Here's my crazy-arse, pie-in-the-sky (you've been warned :lol
, 50 years from now, 28 team NRL:
4 conferences, lets call them A B C D for simplicity.
A: Easts, Souths, Wests, Auckland, Christchurch, Gold Coast, Sunshine Coast
B: Parramatta, Penrith, Canterbury, North QLD, Central QLD, PNG, NT
C: Manly, Central Coast, Newcastle, Ipswich, Brisbane, Brisbane City, Wellington
D: St George-Illawarra, Cronulla, Canberra, Tasmania, Adelaide, Melbourne, WA
(i told you it was pie in the sky...but tbh if i was making a 50 year plan for the NRL, this is what I'd aim for)
2 parallel divisions of 2 conferences (14 teams) each, which rotate on a 3 year cycle.
example:
Year 1:
Messenger Division, Conferences A and B
Churchill Division, Conferences C and D
Year 2:
Messenger, A and C
Churchill, B and D
Year 3:
Messenger, A and D
Churchill, B and C
The draw would be as follows:
Each team plays the teams in their conference Home and Away (12 games), the teams in their opposing conference once each (7 games), and one team in another conference once (1 game, just so its an even 20).
The finals are the old NSWRL top 5 system in each division, with division winners facing off in the Grand Final.
brilliant, right? :sarcasm:
