If we want to sell the NRL to the rest of the world we need to use brands that sound credible.
Western Sydney Tigers
Western Sydney Magpies
The proper noun Sydney has to be in it so people outside of Australia know where it is. Sydney is Australia's most well known city, so let's use that to our advantage.
Money can be made by taking a club that has "Sydney" in its name to overseas markets and establishing some sort of link with the local community. America, Canada or England would be a great place to start. Visit schools and universities during the off-season to teach them about the game. Give the schools a Blu-Ray to help them understand the game, showcase the most exciting aspects of the sport and leave behind some footballs and training manuals so that the schools can add the game to their curriculum. It would leave a huge impression on the students. Provide a foreign membership option that allows signed up members to stream every NRL game live and on demand, provides caps player cards and stickers of the team logo so they can put it on their school bags, skate boards and school books. It's great advertising.
But do not use the name Wests Tigers. It sounds low brow and informal.
