Why do so many recreational golfers not know how to fix ball marks on greens? I had a revelation today at Quail Hollow. It's because they've learned from the pros to use the pros' roto-tiller method. Stab, chew, lift and pack. Am I crazy, right, wrong, or this a subject no one wants to touch? My immediate reaction is that although the pros may or may not know how to repair ball marks for the long-term life of the green, that's not in their short-term economic interests. They're at the course for only a week and all they care about is a smooth surface, grass or not, for that week. If I'm right, what can be done to correct the pros' behavior? If anything? Or, should we just shut up and go home?
