 Ever heard of Michael Malone, who led the Denver Nuggets to the championship last year? Guess who his dad was? Longtime NBA coach, Brendan Malone. And that's just to name a few. Donnie Nelson Jr. Remember, he used to coach the Mavericks. His dad was Donnie Nelson Sr., the NBA Hall of Famer. This is all throughout the NBA. Even on the court, you see Giannis' brother playing with the Bucs.
