Clauset recently turned his attention to team sports, not because he’s a fan (“I’ve never really been a sports person,” he says), but because it seemed like a subject ripe for investigation. With the help of then-PhD student Sears Merritt, Clauset worked to change that. Clauset believes his big-data discoveries could prove a boon to teams and oddsmakers alike.

And so, casting about for a team, he latched on to Dominique Wilkins and the Atlanta Hawks. They were 750 miles away, but through the magic of superstation TBS, Goldsberry could follow them as if he himself hailed from Georgia. Goldsberry went on to get his bachelor's degree in earth science and geography at Penn State, and then a master's and PhD in geography from UC Santa Barbara, where he wrote his dissertation on real-time traffic maps of the Internet.
