Pointed his finger at the ref, said something and immediately backed away. Probably said something like, "you blew that call", or perhaps a more profane version.

I've seen coaches get in a ref's face and be very threatening and actually get physical. Kwhit did none of that from what I've seen. I've never liked the guy, but thought he showed pretty good restraint.

Personally, I would have been more pissed off about my AD walking onto the field and causing a penalty that would have cost them the game if their keep-away antics had led to a TD.
