I am biased being a Cantabrian, but a team down here would definitely work. The population argument isn't a factor for me, we support our teams fiercely and we win.
I’ve been thinking about this recently also being a Cantab and how this could work.
I think entering a team in the NSW Cup would be a good start. This would be the ideal precursor to any viable expansion side. It’s the type of thing being done by the PNG Hunters in the Q Cup.
It would also raise the profile of the game and take the quality of the game up a few notches as well.
A team here would also be another method to developing pathways from the local game and you would also have the beginnings of the derby v The Warriors.
It would need a foot up from the NRL but if they could give a 5 year commitment it would be a massive opportunity of growing the window of the game in NZ and the best chance of an expansion side in NZ working.
