Spot on. Longtime board reader, recent alum, and I am the fan in question here (though this is my buddy's account name). I was seated right behind Guy in the front row and as soon as the final buzzer sounded the refs came over to the scorer's table. At this point I was pretty animated/still in disbelief/livid about what a terrible call that was, how they handed over the game, etc. I did briefly use profanity - "that's the worst f------ call I have ever seen", I believe, but prior to that had kept everything else during the game PG/and was actually fairly quiet. All of a sudden Phillips quickly stood up, turned around, and yelled "sit down and shut up" while pointing at me. I didn't, and he took a step towards me and grabbed me by the collar, totally crazy. Next the fan seated behind me, a gentleman around 50-60 years old, came to my aid as described above by Billikan. I yelled a few more things at Guy (try getting the players names correct, learn how to do your job) who was now busy threatening/screaming at this other gentleman, before I exited without an incident or "scuffle with security" that I think someone else mentioned. The whole scene was pretty unbelievable, you would have thought the ref who made the call was his son or something.
I also know someone who works at Chaifetz/for the University, and was told afterwords that they had to spend 2-3 hours reviewing the tape of what happened and going over the incident, though I'm not sure if anything came from this.
