They're small, but produce lots of players. With the small size of Super Rugby crowds in Australia it wouldn't be much worse hosting a game in front of 1k Tongans or Samoans.
The issue isn't with players. It's with paying attendees, sponsorship and broadcasting agreements... all of that wouldn’t even cover the flights.
Union is broke, the only prospects to grow Super Rugby are even more so.
Once a south island team enters the NRL and takes a large slice of their 1 viable market..Super Rugby as a whole will go into a complete death spiral.
What they're panicked about now is just the start.
It's over for Super Rugby- professional Rugby Union in the Pacific is in serious jeopardy over the next decade.
It will end up being semi pro with only contacted All blacks and Wallabies making the Lions share.
Once the NRL takes over the Pacific and becomes the premier professional sport of the Oceania region, the the NRL brand will be a symbol of the culture of an entire region of the planet and be an internationally recognised brand.
