Nate Silver has written on what’s so great about sports data. In short: it’s rich data (not just big data), we know the rules, and feedback comes quickly.
This is from ESPN The Magazine‘s “Analytics Issue”, which comes out each year connected with the Sloan Sports Analytics Conference in Boston on Friday, February 27 and Saturday, February 28. I’ve been, back in 2013 when I was working for a sports ticketing company; a lot of interesting talks happen there. Most talks from past conferences have been posted online so it’s worth poking around if you have an interest.
