Basketball fans have spent countless hours in the nation's rec rooms and bars debating the biggest shot in NBA history. But now thanks to math and an in-depth analysis by the Wall Street Journal, we have a definitive answer—and it's not a shot that would top most people's lists. A new-ish statistic called win probability added—how much a made basket increases a team's chance of winning—can be shifted to championship probability added—how much a basket increases a team's chance of winning it all. By that metric, Kyrie Irving's 3-pointer that gave the Cleveland Cavaliers a 92-89 lead over the Golden State Warriors with 53 seconds left in Game 7 of the 2016 Finals is the "clutchest NBA shot ever" with a championship probability added of 32%. Even the great Michael Jordan only ever hit a shot that increased the Chicago Bulls' chance of a championship by 19%. Read the full piece here for everything that went into making Irving's shot bigger than the more than 4 million that came before it. (More NBA stories.)
