The Sunday night games 7 aired was all games that 7 would keep. Easter Sunday Night, Kings Birthday Eve, Gather Round & WA Day.
This season is 23 Thursday night games, if they are to have it every round next year then they can lose 2 Sunday night games (probably WA Day & Gather Round?)
Actually this year they had 2 games for Anzac Day, next year that’s a Saturday so they will probably only have 1, so they might only lose 1 Sunday night match.
This from the previous thread mentions 5 Sunday night matches on 7 but I think there was only 4 that actually aired on 7 - Gather Round end R5, Easter Sunday Night R6, WA Day R12 & Kings Birthday Eve R13
