Jim, That would be true, IF, when the boys play the 7800 yard monsters their scores are closer to par. From my perspctive, they seem to shoot lower, relative to par, on the monsters then they do at some of the older, shorter courses. i.e. peblle, Riv, Weschester, and of course Shinnethingy.
My feeling is that Forrest's observation speaks to the significance and importanance of the one-shotter.
But, clearly the PGA Tour has other pre-requisites for the choice of venue and likely feel self-imposed pressure to make golf more exciting to retain what little television revenue they have left.
