If the sample size was say 5 or 6 games, then sure, but not 1 or in some cases 2 games thus far.
Take Bayswater, MetroStars, Broadmedow, Moreton, Canberra, NWS Spirit and South Hobart for example, I would bet the majority of up tick in attendances (especially in game 1) would be from fans of other clubs who are there to check out new league etc and dont have other NPL matches on at the same time. Again, if you get the same crowds in 5/6 games, then yes.
At this point, it seems like only Victorian clubs care about this comp.
