I did a full recap of the dual at The ILLINI Wrestling Blog & Forum & Beyond that includes a video of the highlights. What you noticed is something I also found curious. It happens at :25 in the video:
My first thought was that the ref saw something he didn't want to see like a child walking in on Mom and Dad rolling on the couch, rolling numbers, rock and roll, they got my Kiss records out.
Are there other possible explanations?
Maybe he wanted to make sure it wasn't a choke? Or, perhaps he thought by vacating the ABSOLUTE BEST PLACE IN THE GALAXY TO SEE THAT PIN he could find another vantage point that was even better?
I'm just asking questions.
