So, it's Jayson who's the object of hatred de jour. Before it was Boyes, Strickland, whomever. Look, there are lots of "classless" people in pool, it's one of the things I like the least about the game, but it is what it is. Do I have to list the numerous indiscretions perpetrated by other players, such as cheating etc? Those acts are truely classless.
For instance I remember Appleton getting a lot of flak for his jumping on the table etc in the world championship, I remember not being a big fan of it myself. But you know, he won me over with his tireless work for the benefit of the game. He's a great guy, who for instance helps out people with special needs playing pool. I regret having ever said anything about that display of emotions back then. I don't know Jayson, but I won't judge him on this kind of behaviour alone.
First and foremost people who jump and shout in pool make themselves look a bit stupid, but IMO that is not even close to being the problem with pool. The problem is with other people: Cheaters, Liars, Scam artists....Pool has been f-ed over so many times by crooked promoters that we have come to expect it. Then there are people who dump and fix matches etc. I'd take 1 million Jaysons over those guys. Personally I don't scream and shout much, it's not my personality. If someone does it against me, I wouldn't be thrilled, either. But I can only control my own actions, and there are much, much bigger fish to fry in the pool world.
