Duke/Maryland officials

[Hawks Coach]

I saw what he did and I understood it right away. He pointed directly to the player it went off, confused the announcers who called it wrong, then indicated the direction the ball would go (to Maryland). It then appeared that someone else on the court (or maybe Coach K - he was right by the Duke bench) questioned the call, so he again pointed to the player emphatically then signalled Maryland ball. Not sure if this is a college mechanic, but I think that by watching on TV with audio, the situation was more confusing due to the announcers not knowing what he called.

I have seen the same mechanic used before (maybe by Valentine!) so it didn't seem to me like he was going back and forth, but I can see where it might look that way.
