I'd say that Tee Dubs would probably get marginally bigger crowds if the Nix didn't exist, but it wouldn't be 7,000 more people. The whole argument that the A League is taking money and attention away from the ASBP is based on a false assumption: that the money and attention which the Nix and A League receive in NZ could only be directed to football related activities in NZ. If the Nix didn't exist, would WelNix and Terry S have invested so much money in TW? Would Sky broadcast live ASBP games instead of Nix games? Would Huawei and Carlsberg pay as much to sponsor local teams when they wouldn't get exposure to the Australian market as well? Would everyone attending Nix games start attending ASBP games?
The market in NZ is simply not big enough to sustain a professional domestic league. If there was no NZ-based A League side there would be a large loss of attention and money to football in NZ.
Is there a net benefit to the profile and development of football in NZ from having at least one locally based professional team? If the answer is yes then the Nix/A League hating from ASBP fans is just partisanship (which is fine if you admit that) .
I also don't buy the "FFA will take the Nix away" line - why would they get rid of a financially stable club which gives them access to a market the size of Sydney or Melbourne, right when they are talking about expanding further?
