My thoughts...I don't see a problem with what either one of them did. I think the moment, the pressure, the excitement, heck the environment, would be hard to imagine for most people, let alone a guy 20 years old...I am perfectly fine with him jumping around and getting excited....BUT I am also fine with an accomplished veteran giving him a not so subtle hint that it may not be the best way to handle the situation.
Look, this ain't snooker, or even pool of yesteryear where players wore tux's and the fans whisper their approval for a good shot. In this era of basketball players "posterizing" opponents with dunks and endzone dances that last longer than the scoring play, (right or wrong) fans want to see raw emotion and in your face drama.
Most on here would watch a stream of these players playing the ghost at the local bar and grill, but the casual fans, the ones that pro pool needs in order to become a viable profession again, want to see things like yesterday. I only wish the announcers would have addressed it in detail (maybe they did and I just missed it). Send the girl over and get interviews and ask what happened. Explain, in the off chance that there were casual fans tuning in, why it happened. Again, just my opinion.
