In 2008–09, Granger became the first player in NBA history to lift his scoring average at least five points per game in three consecutive seasons, and the first Indiana player to average more than 25 points per game in more than 30 years. He ranked fifth in the NBA with 25.8 points and was named the NBA's Most Improved Player. His average was the highest by an Indiana player since Billy Knight's single-season team record of 26.6 points per game in 1976–77. Granger scored 20 or more points in a career-high 16 straight games from December 15 to January 19, tying the longest streak in the Pacers' NBA history. In a three-game span from January 3 to 7, he scored 35 or more points in each game and is the only Pacers player to ever do so. In February 2009, he played in his first and only NBA All-Star Game. He missed a total of 15 games due to injury or illness, including 11 in February and March with a torn tendon in his right foot.
