My wife got comp tickets to the Miami game some time ago, so she gave them to me, along with plane tickets, as a birthday gift. Our seats happened to be directly next to the gate to the stairs that lead to the announcers' crows nest. (Kinda crappy seats, but the price was right.) So, I saw and talked to CA three different times coming and going.
While I too find him annoying as a commentator, he couldn't have been nicer to me. Stopped and talked every time, complimented Duke, asked if my wife and I needed anything, etc. Even turned away from the floor a few times during time outs to give me a thumbs up. So my annoyance with him will now be muted a bit.
