Sully, I asked the same question during yesterdays telecast. One answer was about the humidity levels. But, I suspect that's hogwash, too.
The reason the greens were receptive and a tad slower (IMO) than in years past was all about creating an exciting tournament.
I'm on record as predicting the Aces on 16. Why did, or How did I know that? Well, It seemed rather obvious that the goal of the committee was to get the roars back. From the love fest coming from the media this morning, I'd say the committee hit a home run. What's fascinating to me is how nobody realizes (questions) how they have been manipulated into feeling this way. (save for you of course) Maybe it's enough to feel all warm and fuzzy, but to me, I'd feel better if it wasn't the hand of man that had so much to do with it.
