There have been 4 Jazz players to don the #21. The very first was Rick Adelman in 1974-75, when he played 21 minutes, shot 2.1 FT's, and had 2.1 personal fouls per game. He also shot .421. Rick Adelman also has 21 full seasons under his belt as an NBA coach.
The last player to wear #21 was David Benoit, who retired from Utah in 2001.
The Jazz have picked three players at #21: Pavel Podkolzin ('04), Eric Murdock ('91), and Bluuuuuuuuuuuuuuuuuue in 1989.
14 players currently wear #21, 2 who I wouldn't mind the Jazz signing as free agents this offseason:
