Best NBA players to win NBA Finals with two or more teams: 6. Robert Parish
Known as “The Chief,” Robert Parish was one-third of the dominant Boston Celtics trio that won three NBA Championships in the 1980s. He was a blossoming player who was traded to Boston as he was starting to take off with the Golden State Warriors. Parish was coming off consecutive seasons averaging a double-double (17.2 points and 12.1 rebounds in 1979 and 17.0 points and 10.9 rebounds in 1980) and was ready to explode into being an All-Star.
Parish was selected to nine All-Star games and two All-NBA teams as a member of the Boston Celtics and was absolutely dominant. He posted a stat line of 16.5 points, 10.0 rebounds, 1.5 assists and 1.5 blocks per game over 14 seasons with the Celtics. At age 41, Parish was not quite ready to call it a career and moved into a reserve role, first with the Charlotte Hornets for two seasons.
At age 43, he signed with the Chicago Bulls to play his final season. Parish only appeared in 43 regular-season games for the Bulls and only played 9.4 minutes per game. He also only appeared in two playoff games, but that was enough to make him the third-oldest player to ever play in an NBA game and the oldest to win an NBA championship. Even if Parish is almost exclusively remembered for playing alongside Kevin McHale and Larry Bird that does not take away from the special nature of that accomplishment. It is the type of achievement that is unlikely to ever be duplicated unless someone else, later on this list, has something to say about it.
