The three letters for the #NRL tags all come from what's on screen when you watch on FOX (except Canberra).

Now some of these should be easy & obvious changes; like Bris, Storm, Parra, Titans, Souths, Dogs, Wests, Drags, Manly, NZW, NQLD but others needs a fair bit of thought...
Look at the difference in the tag styles. Every single one of the AFL tags is easily identifiable as an AFL team. Compare that to NRLCanNew or similar. Surely we can come up with some better tags for our own teams?
