I was a fan of women's pool even back then. I know both Robin and Jean and have heard both their accounts of what happened. Despite all this, there remains a lot of room for speculation.
It's all true. Jean made a few remarks that Robin didn't like and a protest was filed and a fine assessed. Jean refused to pay it, but the story of why she gave pro pool up requires some speculation. After all ---
1) Jean was a gifted all-around athlete, especially proficient at basketball, golf, and bowling, and craved to compete in many areas of sport.
2) There was little left for Jean to achieve in pool and nobody ever emerged that could compete with her for #1. Allison Fisher has had Karen Corr to push her for the last seven years, but nobody ever threatened Jean's domination of women's pool.
3) One must consider the possibility that once Jean had been away from the game for a while, she didn't really miss it. While her refusal to pay the fine assessed against her was the initial reason she walked away, I suspect the reason she stayed away is that she realized she didn't miss women's pro pool.
Although the story wasn't written this way, in so many ways, Jean walked away on her own terms, atop the sport and indisputably the best ever in her sport.
Jean Balukas and women's pro pool are thriving today, and here's to a great future for both.
