According to the Elias Sports Bureau, there have been more than 2,500 instances of a player in the shot clock era (since 1954-55) taking at least 25 true shot attempts in a playoff game.
Among those games, Dirk Nowitzki's 93.9 percent in Game 1 was the highest true shooting percentage, by far. Next closest was Vince Carter’s true shooting percentage of 82.5 from his 50-point game in the 2001 playoffs against thePhiladelphia 76ers.
Expanding the sample in which a player had 25 true shot attempts in either a regular season or playoff game since 1996-97, there are more than 8,500 such instances. Incredibly, Nowitzki’s Game 1 is still the highest in that span, beating out Ray Allen’s 90.1 mark from a 2002 regular-season game against the Charlotte Hornets, in which Allen scored 47 points on 15-for-23 shooting from the floor and 7-for-7 from the free throw line.
Nowitzki shot 12-for-15 from the field and 24-for-24 from the free throw line in the Mavericks' 121-112 victory in Dallas.
