I don't really know why Nine/NRL can't start implementing something like this to meet the two hours of 'NRL on Extra' content they're contractually obliged to deliver:
Monday: Sunday Football repeat
Tuesday: NRL Full Time (Highlights show aired internationally)/'From the Vault' - Footy Show (collection of old discussions/segments/sketches from previous years)
Wednesday: 'From the Vault' - Viewers Choice (Simple poll on WWOS Facebook/Twitter pages listing four games with a common theme [eg; 2005] & most popular gets aired)
Thursday: 'From the Vault' - Weekend Lookahead (A previous match-up involving the two teams featuring in FNF or SF)
Friday: Footy Show repeat
Saturday: Friday Night Football (QLD game) repeat
Sunday Friday Night Football (NSW game) repeat
Of course this schedule can be changed in weeks leading up to Origin, the Finals and into the beginning of a new season. In addition, over time new features can be introduced into the schedule like having 'Directors Cut' repeats of FNF/SF using the camera angles featured in Jump-In during Origin or airing some press conferences from the different teams.
Although this is just a basic idea on how the content can be introduced quickly and please all parties by Nine fulfilling their contract, NRL getting extra exposure & fans being able to watch classic matches along with catching-up on games/shows.
