During his first two seasons in the NBA, George played mostly the shooting guard position. However, with Danny Granger missing nearly the entire season due to knee and calf injuries, George began playing the small forward position and became the go-to offensive option for the Pacers in his third season. On November 21, 2012, George made nine three-pointers en route to a career-high 37 points in a victory against the New Orleans Hornets. The nine 3-pointers broke the franchise record for most 3-pointers made in a single game, surpassing Hall of Famer Reggie Miller. George was named the NBA's Player of the Week for the first time in his career in December, winning three straight games against Cleveland, Philadelphia, and Detroit. He recorded his first career triple-double in a victory over the Charlotte Bobcats on February 13, 2013, finishing with 23 points, 12 rebounds, 12 assists and 2 steals. That same season, George was selected to play in the 2013 NBA All-Star Game in Houston for the first All-Star selection of his career. He recorded 17 points, 3 rebounds and 4 assists on 7-of-13 shooting in 20 minutes for the East, but they lost to the West, 143–138. George averaged career highs of 17.4 points, 7.6 rebounds and 4.1 assists, and was the only player in the league with at least 140 steals and 50 blocks. At the conclusion of the regular season, he was named the NBA Most Improved Player.
