Cool video on point differences in the NBA

At the end of regulation, tied scores are about twice as frequent as what you would expect from a strategy-free, i.i.d. scoring model. Using data from the last 13 years of NBA games, Cheap talk (a blog by two professors at Northwestern) presents a video which depicts how the spike emerges at 0 in the point difference distribution, over the last 40 seconds of the 4th quarter. A similar video shows that no such spike emerges at halftime — a great visual demonstration that strategy matters.

Thanks to Patrick Warren for the link.
