Longest-Tenured GMs In The NBA

October 17 2012 at 1:28pm CDT By Luke Adams

Over a quarter of the NBA's 30 teams have made significant front office changes since the 2011/12 season ended, with nine clubs hiring or promoting executives for their general manager openings. But while many teams are making changes, a number of GMs have been with their current franchises for years, or even decades.

Most of their names at the top of our list of longest-tenured GMs are to be expected — Pat Riley, Joe Dumars, Mitch Kupchak, R.C. Buford, and Danny Ainge make up five of the top six, and each have brought championship banners to their respective franchises since taking over. Still, there are a few surprises, including the number one longest-tenured GM: Geoff Petrie of the Kings.

Not all of the executives listed below necessarily have the title of "general manager," as many top execs are their team's president of basketball operations, or hold a similar title. For clubs that have both a a general manager and a president of basketball ops, the GM is listed below, with the president indicated in parentheses.
