I'm becoming sick of all these Oak Hill is poor type threads. Sorry for this rant:
While options are considered great in architecture, I find that a "one-obvious-route" type of golf course works for pro golfers.
A tournament is seeking to find who plays the best under the circumstances. If the circumstances call for precision, shot shaping, and a pure ball striker, then that is what it will take to win that given week.
As fun as it is to watch the pros play a course that makes them think and have options, it doesn't mean that this has to be the way to determine the winner. Sure, we would love to watch them play Pine Valley, NGLA, LACC, ANGC, the Bandon courses, Sebonack, etc., every week, but they could go play a muni or a par 3 course to determine who is playing the best. So what if they played a tree lined course; the guy who played the best won. Congrats to Dufner for playing better than every other player, even if it was at Oak Hill.
