Yeah, the majority of sports teams around the world make losses and rely on rich owners' generosity/vanity.
Since the league almost died in 09 BA seems to have been working with clubs to minimise losses as a first step. If a team loses $100K and four owners have to put in $25K that can be seen as a worthwhile investment in owning a team.
If the club loses $400K and they are having to put in $100K that can get very old very quickly if the dose is repeated.
Cairns, Perth and NZ all look set up for potential profits this year if they have good seasons on court, Adelaide and Wollongong could be somewhere close if they perform well and attract fans too.
Townsville could but they seem to have alienated some chunks of their support base which isnt good in a small town, nor is the unrealistic expectation that anything but a GF is a failed year. Had they won GF3 at home in 2001 and SF3 in 2011 things might be very different for that club.
The big thing is getting more league revenue to promote the NBL and also give out some sort of dividend, not matter how small.
The new Ten and NBL.TV deal (which also brings significant new revenue) are good for retaining expiring sponsors and attracting new ones which should help a lot in that regard.
The next 2-3 years will be pretty big in deciding whether the league continues to grow to be a strong second-tier sport or has to find a niche as an almost semi-pro competition.
