I just don't get why clubs think this will make them more popular.
Melbourne AFL clubs with 1 exception haven't done that. Canterbury, Manly, Parramatta and St George aren't doing it. All those seem to be doing fine.
What kind of genius would wake up one day and be like "Gee I couldn't follow them while they were called "Penrith" because I loathe that suburb with every fibre of my being. But now they are "Western Sydney" I'll happily drive to PENRITH every fortnight to watch them play. I'll buy a jersey and a membership as well".
Dropping "Eastern Suburbs" didn't turn Easts into a powerhouse. The Dogs and Balmain tried it and saw it was stupid.
What happens if the Panthers do that and the next day Canterbury, Wests Tigers and Parramatta all want to do the same thing because they don't want to be overshadowed?
These silly namechanges to try to broaden your appeal have a history of failure, stop trying it.
