Good point RugbyFuture and i do agree, i guess my only point for this is that in the initial years when the competition is establishing itself, leveraging existing resources by aligning the clubs to Super Rugby teams allows economies of scale and minimises operating costs.
For example, for the Greater Sydney Rams to run a team with the same support staff and facilities that teams like the Spirit and Rising had it would cost them another $250'000/annum, yet the Rising and Spirit were able to leverage their current staff and resources to do that for no additional expense.
Perhaps in the future(next 2 to 3 years) it would be in the best interest of the competition for the QRU, Rebels, Force to look to offload the NRC teams to private investors or other parties if the demand warrants. Brumbies did this partially through the Vikings partnership, there might be similar opportunities for other teams in the future.
