We should have mini cup games inside the league with their own tables. Two obvious ones are:
Queensland Cup - 12 games per season - with matches between Cowboys, Broncos, Titans, Dolphins
In Round 25 - schedule Dolphins vs Cowboys & Titans vs Broncos etc - 1 of those games will likely decide the cup winner
Western Sydney Cup - 12 games per season - with matches between Bulldogs, Panthers, Eels & Tigers
In Round 25 - schedule Bulldogs vs Panthers & Eels vs Tigers etc - 1 of those games will likely decide the cup winner
It makes those 12 derby games each season have an additional meaning.
Similarly you could do:
Eastern Sydney Cup - 12 games per season - Sea Eagles, Roosters, Rabbitohs, Sharks
Round 25 - Rabbitohs vs Sharks, Roosters vs Sea Eagles -
Knights, Dragons, Raiders - regional NSW/ACT teams
Warriors vs New Zealand 2
