The greens are in great shape -- and I am sure they are very firm being so new. I was told that they were rolling 12.5 today, and depending on conditions, will likely get faster towards the weekend.
Most of the talk I have heard is that the average score will be much higher with these greens, but these guys are so good, the winning score may not be that different from the past (as one or two of these guys can be on fire any given week and go really low).
Just my prediction, but rather than close to twenty under as in the past, I suspect it will be closer to 12 or 15 under. Just walking around, I noticed the bermuda rough was thick too -- lots of rain and heat lately. Should be interesting.
