Based on Mike Davis' comments at the USGA press conference at the Open, it looks like TP will play around 7585 yards par 70 for the Open next year, with 6 and 18 par 4s at 515 and 525 yards respectively.
For those who aren't Southern Californians, we have something called June gloom. Basically, it is a weather condition whereby the marine layer moves in late in the afternoon/evening, then malingers throughout a great part of the next day, sometimes not burning off at all, meaning a brutally overcast day, cool and no breeze. If there is June gloom (a condition that will really sock in TP based on its coastal location), then something 280 or below stands a pretty good chance. If it is the weather pattern we have experienced over the past 4-5 days, then perhaps 280-284 will be the target score. Regardless, if I was a player and offered 280 and not hit a ball, I'd take it.
At this point, it is a matter of whether the kikuyu rough takes to its new locale and can grow. Without the killer Winged Foot and/or Oakmont rough, TP will be exposed no question because the greens aren't all that severe.
Just keep in mind that, for the Buick, when they play it all the way back, the top guys don't beat up TP with plenty of 67s, 66s, etc. A good round is a 68. Furthermore, they have never played 4 rounds at TP all the way back yet.
I have it playing as follows:
450/385/195/485/450/515/460/175/615
405/220/505/615/435/480/230/440/525
From what I understand, there will be more forward tees for 6 and 18 depending on weather conditions, etc.
