In the following season, he scored a career best 31.1 points per game, but the Hawks slipped to fourth place. After missing 30 games because of injuries, Pettit ended his career in 1965 still near the peak of his game. He was the first NBA player to eclipse the 20,000 points mark (20,880 for a 26.4 average). Of the 20,880 points he scored in the NBA, 6,182 of them (nearly 30 percent) came from free throws. His 12,849 rebounds were second most in league history at the time he retired, and his 16.2 rebounds per game career average remains third only to Wilt Chamberlain and Bill Russell.
