Tracy McGrady being inducted into the Hall of Fame without having his number retired by any of the seven franchises he played for is just the latest development to shine a light on the quirks of the various jersey retirement practices of NBA teams. Earlier this summer, the Memphis Grizzlies announced plans to make Zach Randolph's No. 50 their first retired number, despite Randolph still being an active player (he signed with the Sacramento Kings as a free agent after playing the previous eight seasons in Memphis).
There are nearly 200 retired numbers across the NBA's 30 franchises, ranging from 00 (Robert Parish for the Boston Celtics and Johnny Moore for the San Antonio Spurs) all the way up to 1,223 (Jerry Sloan's coaching win total with the Utah Jazz).
