Living in Binghamton at the time the dress code thing went down I understood that somehow Jean did not know before the tournament that formal wear was required. Jean is not/never was a "drama queen". You can bet that the other girls were very glad to have her not compete. If it was a matter of "let the best player win", Jean would have been allowed to compete. You have no idea just how "catty" the WPBA was at that time. That said, there was a similar attitude toward Lori Jon Jones when she was at the peak of her game. Lori Jon just never made any waves. Jean was a class act all the way.
The article is not very accurate in my opinion, for one thing they called the tournament where the dress code thing came about "The Binghamton Classic". It was never called that, it was the B C Open 9-ball Championship, for starters.
