The Tour's motto should be These Guys are Long, not These Guys are Good. They are of course good, too, but their length off the tee is scary these days.
Somehow I think that COR alone is an inadequate measure of the driver's ability to propel the ball far. Is COR tested at all swing speeds? Combine better drivers with better conditioning of many guys (save for Daly, but he's a freak of nature), better balls, and you have reduced many tournaments) to putting contests on slick greens.
I really love seeing these guys play an important tournament in howling winds and horizontal rain. That negates much of their length. Golf as it oughta be...
