Since 2008, the three-point arc has rested at 20 feet, 9 inches from the center of the basket. The international three-point distance had been tested in the National Invitational Tournament the past two years, and the results from the further distance compared to those from the regular season were negligible.
Teams in the NIT converted long-range attempts at a 33 percent clip compared to a 35.2 percent mark in the regular season. The 32-team field attempted 23.1 3-pointers during the postseason tournament compared to 22.8 attempts during the regular season, too.
