Baseball history is replete with superstars who were difficult personalities, head cases, and downright SOBs to the fans, their teammates, and the media.
Babe Ruth made rude gestures to fans and even went into the stands once after one. The list is enormous.
The difference between now and then though, IMHO, is the media, and the amount of exposure these situations would get.
They didn't have ESPN back then.
When I look at guys like a Belle, Guillen, Dukes,and so many others with similar traits/personalities, it makes me wonder what makes them that emotional ticking time bomb? Their background environment, and how they were raised? It always seems to point to a maturity issue that leads to this self-destructive behavior.
Team shrink time?
