10 years ago, i would have thought this might hurt the tour. but there are so many young guys out there now, this might actually help. you might lose one guy at the top, but you open the opportunities for young guys who might not have made it in to the tourney the opportunity to make a name for themselves. there aren't going to be players like Spieth every year, but at the very least you'll have guys who have the chance to do something like he did.
also, it will give "lower" stars the opportunity to breakout and become superstars. if players like Fowler, Dufner, Keegan, etc.... breakout, that helps everyone.
