I think you're wrong. Personally I loathe league, But I have watched SOO and the grand final because I'm on the couch when it's shown. If those league matches were on a Saturday arvo, I wouldn't be watching the Tele so I wouldn't see it.
I don't get why you would watch something you loathe, seems a bit silly to me. Especially when there are other things on like Sunday night on 7 and what ever movie 10 decide to show. Plus movies on 11, GO and 7 mate.
If you don't like something there are hundreds of other alternatives to do. Even Bunnings and Coles are open when the GF is on.
