Jay,
Your opinion about how you see the Open set-up at Winged Foot is well-thought out, just a bit incorrect!
Mike Davis is definitely putting his mark upon the course set-up in taking over for Tom Meeks, but what most commentators are missing is that the VAST majority of this years set-up was done by Tom Meeks.
He is the one who worked with the club in creating the fairway lines and dimensions and these were cut and in place since early last year.
Where Mike's work will show up the most will be on the greens. He is not planning on turning them into cement, rather he wants them to be about 11 and no more, with several greens in the 10-10&1/2 range. By doing this the choice of pin positions and areas of the greens that can be used will be greatly increased. It will also allow him to consider using areas on the greens that have now been restored and recovered (think back left corner of #10).
The added length and new tee box on #12 was the idea of the club, not the USGA. Mike wants to find ways to have the course play as the architect designed it. Tilly made the 12th hole to be a reachable in two shot par-5. In 1929 both Espinaoza and Jones went for it in two all 5 days. In 1997, both Tiger and Davis went for it in two on Sunday and each ended up in the rough just right of the right-hand greenside bunker. Both took 4 more shots to get their ball in the hole from 50 feet away and made bogey.
I believe that Mike is on the right track for how to create a challenging course to "define" the best player in the world and it will be interesting to see how his ideas impact and ashape this quest in years to come.
