Minimal rough is a great concept if driving in the wrong position creates a significant disadvantage when trying to hit the approach close to the hole. Otherwise, the ability to drive with length and accuracy, long a hallmark of championship golf, becomes irrelevant. At Medinah the trees provide some dterrent to wild driving. the problem with the new equipment is that the increased length coupled allows short irons which are easier to hold greens. This requires rock hard greens to create the challnge. I dislike the overemphasis on rough but I understand it more, not as a means to protect par but as a way to reward good driving.
