One thing that has always annoyed me, especially during winter when outside courts are mostly unusable, is that stadiums always have organised games on every court and never set decent court space aside for some practice/ warmup rings (I mean enough room for at least one half court pick up game).
So for example, I am saying that if you decide you need three courts for organised games, the stadium should be built to house the extra practice space as well.
This would be great, firstly for people who want to warmup and get their eye in before a game, but also so people who just want to play some pick up or work on skills, can do so whenever they want to.
I realise that they probably don't do this, because economically they probably want all court space being used by paying players, to ensure the most rapid return possible on the stadium. But I would think you could still make it work economically - it would just take a little longer to recoup costs. If necessary you could mitigate this by charging people a couple of bucks at a time to use the practice court - or even a stadium membership option.
I reckon if this option existed, over time you'd see a lot more people with improved skills and you'd be more likely to build a bit of a 'gym rat' culture. Both of these things will help basketball in this country in terms of better players and more people supporting the NBL and grass roots basketball.
