The thing that got to me was when Bernie said that she quit playing competitive golf a few years ago. Huh? Then why are you on the show trying to win an exemption into an LPGA event? Then on top of that, the group with the non-competitive golfer wiped the floors with everyone else. It is obviously just one event, but it still doesn't say much for everyone else.
I am guessing that the talent pool that Big Break had to choose from was much shallower for this edition, since they had to find people that had an existing relationship of some sort with another golfer. If the #11 Duramed finisher, for example, wasn't dating/related to/etc another golfer, she wouldn't be able to be on the show no matter what, since there would be no one with whom she could partner. The producers were limited by the group nature of the show.
I also don't think the comparisons to Kim Welch are valid. It was obvious that she had talent, even when she was having her mental issues.
