Now, I don't see that happening, either. Why would the players voluntarily accept a limited distance golf ball, and how would that even work - the USGA has a list of approved golf balls.
Also… reduced distance balls will not affect everyone equally. Some players will lose more distance relative to others given different launch conditions, some will have a harder time with the change in spin, etc.
