A toned FBvian drops some knowledge on us:
The reason that you won’t see more celebrities sitting courtside at the Mavs finals is because the courtside ticketholders are not giving up their seats. My personal trainer [ed: ooooh, fancy] trains Don Carter’s daughter. She claims (this is second hand, mind you) that Jack Nicholson called Don Carter asking to have his seats. (Carter sits in the front row about eight seats to the right of half court.) Carter apparently told Nicholson to pound sand.
