David your third line could be how many will hit Rusacks and go OB trying to go for the green.
When I played in the Dunhill 15 years ago, one of the pros in our group [who was well under par for the day] blocked his tee shot into Rusack's, but somehow it came back onto the course.
As we walked off the tee I gave him a wide-eyed look, and he said he had a last-second fear that he would drive it through the green and o.b. because we were very downwind, so he quit on the shot and blocked it right. It's a good bet that someone will do that again this week, though hopefully not someone in contention!
