Note: I am not a web developer, so this project has been mainly to teach myself a new technology (Rails, primarily). It is very much a work in progress. Also, clearly, I am not a designer and am not really sweating that for now.
But when you're finished, hawk this on /r/nba. Lots of devoted fans there, and contributions are very much appreciated.
If anyone has any tips for serving up a site like this with limited resources, feel free to teach me.
Either way, it's a good problem to have!
Many of these sites serve up their play-by-play on a JSON feed, which makes it even easier. However, I must warn you, the data is not as clean and robust as you may like. A large part of my work was implementing a cleaning algorithm to infer missing data.
