I think there are 3 basic groups of supporters. There are those who don't feel any real connection to a particular team ( and if you lived in Darwin for eg why should/would you) but love and appreciate the game and just enjoy watching good footy.
Then there are those who love the game and recognise and appreciate good footy regardless of which team is producing it but still follow one particular team year in year out.
Finally there is a third group for which it is a purely tribal thing and who support a particular club year in year out. For supporters in this grouping their support and loyalty is more to the club then it is the game. This grouping would include those supporters who if their club folded would walk away from the game and stop following it.
In respect of the first group they often get accused of being band-wagoners because they seem to switch allegiances and seem to support whichever team is doing well at the time and so people from the tribal supporters tend to get on their high horse and look down on them. But really, the only reason they switch teams is because they don't have a geographical reason, or family tradition of following a particular club and because they love watching good exciting footy they are obviously going to be attracted to the team/s doing well, for the simple reason that if a team is doing well they are most likely the team that's playing good exciting footy.
Personally think I think people in this grouping are more true R.L. lovers and followers than those tribal supporters whose support is based purely on where they live and family tradition.
So, if you are one of that first group don't worry about comments of those here who crap on about band wagoners most of them are numbskull' who know b*gg*r all about the game anyway.
For the record I belong to the 2nd grouping, live in Brisbane and support the Broncs but if there was no Brisbane team in the NRL I would probably be a band wagoner to, but having said that I think it is more interesting/exciting and ultimately more satisfying if you do have one team to support and follow year in year out.
