Speaking as a person with this experience.
I still follow League. Why? When norths got kicked out i was 10, i still love the game (despite it not being near what it should be). My team is North Sydney and i follow them in the NSW Cup.
I dont watch it on TV much, too many times there are sides i have no interest in watching on, or they are boring to watch.
My favourite places to watch football are at a packed SFS (or even and SFS with over 10K), preferable on about half way, opposite side to where players enter field (bay 34-36 roughly i think), just because it supurb viewing and a great atmosphere, especially on Anzac day, and Leichhardt Oval, because it to me is what footy is all about, going along in droves, on the hill, at a great, picturesque suburban ground. I also dont mind Win just cos its local.
Hate ANZ stadium, it is everything i dislike about footy, fake feeling, no atmosphere, sh*tty seats. Cant stand the guesthouse.
As far as clubs go, dont really follow anyone in the NRL. If anyone easts i guess, and i like watching the Tigpies play because they play the best football, this is more a process of elimination because of there being so many scummy clubs (manly brisbane melbourne NQ Cowboys canterbury).
Im still disgusted by the treatment of my side by the NRL, however, and despite attending games i dont purchase or read the sh*tness of the telegraph or subscribe to Austar at all.
