If I were a woman who could drive as far as the guys (someday there will be one), why should I be stuck playing in the LPGA for less money and with lesser competition? If she can compete with the guys, playing by the same rules, and with no special treatment, then I say let her go for it. And may the best player win.
This hypothetical woman you speak of would make much, much more money on a tour (the LPGA) she absolutely dominates than on a tour (the PGA) where she's just "one of the guys." Perhaps 20 times as much money. That's reason enough to stay put, don't you think? Secondly, you're making a huge supposition -- that a woman can both drive as far and
play as well. I'll believe it when I see it.
Do you also think that the Williams sisters should try their hand at the men's tennis tour? Their serves are clocked at higher speeds than at least half of the men on tour.
