I thought Doc mentioned the game would start before 6:30 to disrupt the Nine/Seven news (if on 10).
6:30 on Nine/Seven makes sense though.
You're right, all depends on the network. TBH I can't see 7 or 9 wanting a Sunday evening game. Managing the North/Feebleball states divide is just too hard to do - you can only do if you own both NRL & AFL rights and split the feed.
However Foxtel would go for it - anything to pull viewers away from the F2A's strong ad revenue night.
Really though Sunday is about the news cycle. Viewers are more inclined to 'reset' their news channel on a Sunday after the traditional weekly drop off on Saturdays so by having a strong lead in 7 & 9 have been able to pretty much dominate Sundays shutting 10 out.
So looking at possibilities vs effect -
9 win Sunday arvo doubleheader targeting NSW & QLD - win Sunday nights in those states minimum, most weeks national, pull viewers Monday - Friday for next week's evenings
7 win Sunday arvo doubleheader targeting NSW & QLD - win Sunday nights nationally most weeks, pull viewers Monday - Friday for next week's evenings
10 win Sunday arvo & Sunday evening (5:30pm onwards) targeting NSW & QLD - and tie it together with their strongest programming line up - win NSW & QLD, have a tilt at national, pull Views Monday-Friday.
10 wants all 8-9 games but it really only needs 5 slots - Sunday arvo, Sunday twilight, Monday or Thursday night, Friday night double headers - to have a massive impact against its rivals. The extra 3 games though allows them to target markets more effectively.
