I don't believe there's anyone working that has 30 years in. Hue Hollins, (Scottie Pippen's best friend
), has 27 in and he's retiring. Most of these guys get out before they hit 30 years. Hugh Evans, and Jake O'Donnell come to mind as officials who retired at the 27, 28 year mark.
But it did seem that it was a very veteran crew, considering the younger groups we've seen working together.
