Promoting a "fun night with a game of basketball thrown in" isn't necessarily a bad way to get casual fans to come, but it's no way to build a fanbase of rabid basketball enthusiasts. If you can afford pay TV, you might as well watch the NBA. The NBL cannot and should not compete with the NBA; the goal should be to make Australian basketball fans want to watch both.
To a certain extent I can understand what the NBL is doing. I mean, basketball isn't a big time sport down under, and just like what you said what the NBL is trying to do is to try and bring in the 'casual' basketball fans or they're trying to bring in non-hoop fans and to hopefully get them interested in the game.
And from what I understand, the NBL isn't available on free TV anymore? That's definitely bad. Having games on free TV is a huuuuge step in increasing the visibility of the league. It'll go along way in getting young kids and potential fans into the game.
I've watched the NBL before, and the Melbourne Tigers also played a few exhibition games here last year and there's a lot of talent in the NBL. In fact the Tigers and the Bullets were invited to play as guest teams in the PBA later this month, but unfortunately both teams declined due to other commitments.
I think the only thing lacking in the NBL is marketing. I don't know if any of you are familiar with hoops here in the Philippines, but the top collegiate league here, the UAAP, was practically a 'small' league five years ago, most of the fans were the students of the respective schools and their alumni. But when they managed to get their games in the top TV channel in the Philippines their popularity virtually skyrocketed over-night. Now they draw bigger crowds than the PBA, more sponsors and sometimes the atmosphere rivals that of the biggest US NCAA final four matches.
It's about marketing, marketing and marketing. It's not a question of talent because the NBL has it, it's the promotion.
