The average man has a wingspan about 2 inches more than his height. But several NBA players pop off the chart because of their long arms. It's no coincidence that Jazz center Rudy Gobert, who stands 7-1 and led the NBA in blocks last season, has the longest wingspan in the league at 7 feet, 9 inches.
