opportunity comes to those who create it
Absolutely. Someone like Homicide is out there intentionally inserting himself into the NBL debate, trying to make himself near-indispensable in whatever capacity.
My personal preference would be hearing female as well male commentary on all the sport I watch, but I also expect commentary on the sport I watch to be informative, entertaining and balanced. I'm not suggesting shoehorning a token woman in there who's unqualified to be there, but as a large proportion of the crowd are female clearly women watch the sport in large numbers and have something to say about it.
No doubt, but I'd say the commentary is going to come from a mix of factors - expertise, interest/drive and selection by the NBL or media partners. If there was an ex-WNBL player who was keen, they'd probably maximise their chances by running a podcast now. Maybe they don't because they don't fancy their ultimate chances in paid commentary?
But still, I think podcasts or websites are an indication of who has some level of base drive - cost peanuts but take effort. Outside of podcasts, all the sites I can think of over the years have been run by males (And The Foul, Sixers Lounge, OzHoops, Stern Warning, Pick and Roll, etc).
Monique Bowley had a podcast (with Dale Clarke?) way, way back and has gone on to solid media jobs since then, including a lot of popular podcasting in Australia. But she's had the sense to find bigger markets than basketball!
And instead of commentary, the NBL could probably provide better signals to young girls that they can play basketball now. Think of an NBL broadcast and how it is entirely: men's basketball, Globetrotter promos, Hungry Jacks ads. It's not really NBL's primary remit, but promos for local basketball leagues wouldn't hurt. Perhaps that's something BA should be doing - asking for a deal to promote an "everyone can play"-type ad and a singular URL that directs people to club, domestic and social leagues. I wouldn't trust BA to create that - they should get NBL's people to help because the NBL promo videos are much better than the Boomers ones, for example.
