While I can appreciate the appeal of trying to sneak a peek up the short skirt of an attractive female player, that's ultimately not the reason I watch the women play. And if that's ultimately the motivating factor that lures in male viewers, then I don't reckon not tuning in won't impact their ratings all that much.
I don't think it's asking too much of the ladies to uphold a certain standard as far as appearance. To me, it's representative of just how much better the LPGA Tour is these days than it has been in the past, at least as it relates to quality of play.
I commend Commissioner Whan for assuming that his product should command a little more respect than just the occasional eye-candy aspect. Besides, it's not like they've suddenly become a swimsuit model factory for that matter.
