Can't forget Ed Rush who was a longtime NBA official, then Commisioner breifly, then Head of referee development, and now I believe he's a group supervisor.
His son Eddie F Rush is in his 18th season in the NBA.
EDIT-
Doh! I knew Ed's son had something to do with officiating and the NBA so I put two and two together and grabbed his name off the nba ref's website. I humbly apologize. Thanks for the correction. I thought it was odd that Ed's son had been in the NBA for that long but hey, never let the truth get in the way of a good story.
