Shoot, Shivas beat me to the punch; only slightly less Mickey Mouse in my book than the goofy pin on 14.
I think the main thing about 18 today was the pin position -- unlike the short par 4 at Torrey Pines, you obviously couldn't reach the 18th green at the Black, or feed a ball close to it. The Torrey Pines short par 4 played as a true half-par hole, while the Black's was negated by the front pin position and the severe uphill run-up to the green (and the rough). Most everyone put their ball 15 feet or more past the pin, and faced a birdie putt.
For the US Open winner, leading on the 18th tee, to execute a 6-iron/9-iron -- which Miller praised as the epitome of genius (??) -- was a huge letdown after some pretty exciting play that occured on the back nine. I give the USGA and Davis some credit for trying to make something interesting out of a pig's ear of a hole, but today's set-up wasn't it.
