Awesome talent, but......
First, let me say I didn't get to watch the match, but I'm really impressed that Earl plays straight pool this strong (I'm not surprised, though). He's obviously one of the best 9-ball players to ever live. And Johnny is.....well, he's JOHNNY. Been at or near the top of the game since the very early 90's.
As to behavior, Earl quite frankly disappoints me. He was fiery in his younger days (which I had no problem with), but what I've witnessed from him the last 5-7 years seems more mean-spirited. He's started arguments in matches with some of the most gentlemanly players on tour. Earl demands that others show him respect, so he should be the first to reciprocate. On the issue of fans clapping on a player's miss, I think that is often misinterpreted by the player that misses. Most of the time I've seen that occur, the applause really seemed to be for the incoming player. Granted, in Earl's case, that may not be true.
All that said, I don't know Earl, and I've heard a lot of people say good things about him. I just don't think it helps the sport, the fans, or Earl for him to behave the way he does.
