Unfortunately we are very reliant on a TV deal to survive (draws in sponsors, fans, mass publicity, general connectedness for fans) and unfortunately the NBL is not a very attractive option for TV networks.
It's particularly not attractive for a TV Network to sign a deal where a city of 2 million people can be effectively ruled out from being a target market in the slot due to a lack of there being a local team.
A Brisbane team back into the NBL is more lucrative to a TV network. Add a second Victorian team, and more Victorians will pay attention, and it sets up for better rating games such as a Victorian derby.
If the NBL needs to fund Brisbane and partly fund Adelaide, and maybe Townsville (hopefully they can return to their previous stadium for a better deal), then we need other owners to be strong. Perth, NZ, Melbourne are in good financial positions and run well, Cairns and Sydney are running sufficiently by themselves and Wollongong are okay for the time being. If Cowan can bring a financially strong Victorian team, and we introduce another well run team out of Wellington by say, the Wellington Saints owners, then that's 11 teams. 3-4 of those teams utilise the marquee rule to help put money into ensuring Brissy and Adelaide survive, and it helps the league a lot.
If the NBL are going to make sure every game is produced for NBL.tv, then it makes sense for local games to be broadcasted into local areas for TV networks. There's probably more flexibility for this when there is 7mate, 7two etc.
The league should also look into more games, including midweek games and less trainings - hopefully that will bring in more money financially and hopefully the midweek games rate better.
