Mark...I think that the USGA would like to pick Hall and Liu, or two other "kids," to have some continuity for 2015. They did this with Fowler in the past, with Brian Harman and with Spieth. They had each of those guys for 2 Walkers, I believe.
As far as Porter Cuppers go, believe me when I say NONE of the mid-ams have impressed me this year. I think that they were competing with each other, rather than with the field. It may go down as the biggest FAIL of the year for the USGA, even bigger than the FAIL of announcing the Fox deal during PGA week.
