Today you can find all sorts of data in an open format. Most financial data, polling and government databases, just about every baseball play ever played.
However this open data paradigm hasn't reached across the rest of the sporting world. Getting NFL, NBA, NHL and NCAA data remains quite difficult and legally confusing. This is making it difficult to create an open data science interest in professional sports data.
Does anyone know about any projects that are working on making this kind of data easily accessible via API or other database forma?
