I think the NRL should have a subsidy scheme for unpopular match times e.g. Thursday and Friday 6PMThe NRL could start by subsidies for attendance.
If souths for instance average 17k this year at x amount profit, you are subsidised for any loss of profit that comes with a higher attendance.
So if you drop your prices or give away free tickets you can't loss money.
It'll cost the NRL but increase the quality of the product at the end of the day and pay dividends in the end.
The club should make available say 5 - 10k tickets (depending on venue) for just $10 and the NRL should pay the club another $10 for each of those tickets sold. Make the tickets only available for pre-purchase up to a day before the game to get the sales up before the game
