Former NBA big man Sean Marks will join the Spurs as an assistant coach this season. Marks retired in 2011 after an 11-year NBA career. A position on the Spurs' coaching staff suggests he'll have a fruitful career on the sidelines -- Gregg Popovich's assistants have repeatedly been poached by other teams in need of a head coach, including this summer's departure of Brett Brown (76ers) and Mike Budenholzer (Hawks).

Sean Marks is retiring from the NBA after 11 seasons. Marks played for six teams during his career, and he also had a few stints overseas. He expects to take a front-office job with the Spurs, so his career in professional basketball is far from over.
