Assuming all the facts are true about this guy's average and records, after thinking a lot about this and talking with some others, I now believe there are only two explanations for this.
1) This guy is the most blatant cheater of all time. He gamed the system and has the USBC somewhat in a corner knowing that they need to find a legally defensible way to DQ him.
2) He is an "accidental" bagger/cheater who didn't realize what he was doing and what might happen.
Stay with me ... think about it: Most "good" baggers go to great lengths to cover what they do, even intentionally bowling bad in tournaments to hold their tournament averages down and cover their tracks. Yet this guy dropped his average a huge amount in one year AND bowled very well in the Regular Division last year. A "good" bagger would have gradually dropped their average, bowled terrible in Regular Division for a couple of years and then crushed the Classified Division. This is just so obvious ... like a criminal leaving fingerprints and DNA and an ID at the crime scene.
I think it's possible this guy might have bowled in this pseduo-Sport league, dropping his average way down, not really realizing what he was doing, perhaps thinking he was just not bowling good. Then he goes and bowls well again at USBC in the Classified Division.
I am NOT saying I believe this but what he did was so obviously blatant as to be stupid, unless he was only interested in gaming the system for one big killing with the belief that USBC could not stop him.
BIG QUESTION: Does this guy have a track record of winning big money in handicap tournaments before this year's USBC. If not, he might be the accidental bagger, not a blatant cheater.
It is important to note that EITHER WAY HE NEEDS TO BE DEALT WITH BY USBC.
If he is just an accidental bagger he should step forward and say he is sorry and this is not what he meant to have happen and ask to be put in the Regular Division where his career record shows he clearly belongs.
If he is a blatant cheater USBC needs to find a way to do the right thing. What credibility the organization has in protecting the average bowler is most definitely at stake.
