I don't see why the NRL keep the rolling schedule but fix 1game/day each Round. We get the best of both worlds. EVERY major rivalry and big game will be fixed at the start of the year, maximising crowds, giving club sponsors security and ensuring the best TV ratings. The other matches on a rolling schedule allowing the TV networks safety in the programming.
No matter how bad the clubs are going the Bulldogs V Parra will rate, same for Broncos v Titans, Manly v Wests, Roosters v Souths etc.
There is certainty already there for the networks but it isn't taken advantage of by our current deal. The even bigger bonus for the networks is each club can get their minimum FTA TV slot given to them before the season starts, allowing the networks even greater flexibility in their rolling schedules as most seasons we see for example the Sharks play North QLD towards the end of the year when 9 realise they have to show them at some point.
MNF needs to stay, it is another unique prime time slot and it will be worth too much in the upcoming deal.
