Pro Golf is the result of years and years of what I'll call "grooming". You'll not see a pro golfer on TV smoking, or seldom drinking anything but water. You won't see them wearing anything other than pants, and the standard golf shirt, although they show more and more sponsor logos. Payne Stewart, with his "plus 4s" were channeled to stay within the guidelines, while allowing for variety. They (the PGA) have an image that the players need to align themselves with, and for the overwhelming majority, they do, at least while on-camera. Watch any broadcast and whenever they get to the last few holes, all the tournament leaders are talked about like they're saints. I'm not saying that they players are phonies, but they go with the program because the years have shown that doing so makes a golf tournament broadcast more attractive to sponsorship, and that means more money for the prize pool. Everyone wins.
