The Utah Jazz began play in the 1979-80 season. Maravich moved with the team to Salt Lake City, but his knee problems were worse than ever. He appeared in 17 games early in the season, but his injuries prevented him from practicing much, and new coach Tom Nissalke had a strict rule that players who didn't practice were not allowed to play in games. Thus, Pistol Pete was parked on the bench for 24 straight games, much to the dismay of Utah fans[16] and to Maravich himself. During that time, Adrian Dantley emerged as the team's franchise player.
The Jazz placed Maravich on waivers in January 1980. He was claimed by the Celtics, the top team in the league that year, led by rookie superstar Larry Bird.[17] Maravich adjusted to a new role as part-time contributor, giving Boston a "hired gun" off the bench. He helped the team post a 61-21 record in the regular season, best in the league. And, for the first time since his early career in Atlanta, Maravich was able to participate in the NBA playoffs. He appeared in nine games during that postseason, but the Celtics were upended by Julius Erving and the Philadelphia 76ers in the Eastern Conference finals four games to one.
Realizing that his knee problems would never go away, Maravich retired at the end of that season. It is noteworthy that the NBA instituted the 3-point shot just in time for Pistol Pete's last season in the league. He had always been famous for his long-range shooting, and his final year provided an official statistical gauge of his abilities. Between his limited playing time in Utah and Boston, he made 10 of 15 3-point shots, a sizzling 67 percent.
