And docbrown, regarding your point about QLD Cup matches being shown to boost the Brisbane metro ratings figure for the 4pm match, if that's the case, I'll be very surprised if the Broncos get any Sunday 2pm matches on Fox in order to avoid a clash between the matches. If the Broncs get any Sunday games, it will have to be the Ch9 match.
That would assume some kind of coordination between the different parties...
Luckily (or unluckily) the Broncos will have a Friday night game almost ever week so it's probably not going to happen.
With 4 QLD teams they could set it up so that the two Brisbane clubs alternated between Fridays & Sundays so that every second or third week there's a Sunday game at Suncorp whilst still maintaining the Brisbane presence (home or away) on a Friday night.
Cowboys home games should be Saturday night with at most 1 home game in the first 5-6 rounds. Cowboys away games typically on a Sunday arvo/night or Friday night if a derby or potential blockbuster.
Titans home games typically Saturday night or Sunday arvo/night. Away games similar except if a derby or blockbuster, then Friday night.
Schedule the draw so two home games in Queensland each week and two away games. Only one game in Brisbane itself a week at most - so most weeks either Brisbane & Townsville or Brisbane & Gold Coast.
A QLD derby match on a Friday night every two to three weeks. A few weeks before the first origin have two QLD derbies in the same round (akin to a QLD selection trial) featuring the new rivalries - Brisbane II v Cowboys, Broncos v Gold Coast. Leave the bigger derby games (Broncos v Cowboys, Broncos v Gold Coast, Broncos v Brisbane II) for the non-origin period.
Play all derby games home and away (12 total per year) with each QLD club having 3 home games that are QLD derbies.
