I watched two NBL games on TV over the weekend. The halftime entertainment at one game seemed to be an opera singer belting a few numbers out at halfcourt while a purple anthropomorphic beverage cup capered around nearby. The other was a game featuring dwarf and midget players, some of whom were not bad.
Apart from that, though, it's much as rawr said - there's a weird cargo cult mentality of trying to recreate what they think worked in the 90s. They seem to think that the NBL was popular back then, not because basketball was in fashion and people enjoyed watching the game, but because they provided a colourful ''family entertainment package'' with loud music and mexican waves and cheerleaders and cavorting mascots and so on and so on, so that the wife and kids would always have something colourful to look at and wouldn't get bored.
Having said that, the standard of the game is actually pretty decent. It's certainly not the NBA (especially the overall level of athleticism), but there are some very good players, and it's generally entertaining to watch.
If you reckon you can manage to refrain from stabbing anyone when they play ''I like to move it move it'' multiple times, or announce some idiot kids' birthdays over the PA, I'd say it's worth catching a Sydney Kings game. They've got a bunch of good local players, and one of their imports is Horace Grant's nephew Jerai, who averages about 6 high-flying dunks a game.
