It may be like tennis, in the 70s probably at least 7 or 8 of the best players in the World were Americans, now, you’re lucky if it’s one or two. The same could wind up happening to golf, as well.
Yes, it could happen in golf. But I’d hope not. Golf is immensely more popular than tennis. It has a much broader base to draw from (as well as develop). What I fear is a disinterest developing in that base when shown repeatedly we just can’t contend. We need contenders, and not just a fortunate few. If anything, that’s what the PGA’s legacy should be. As I noted, after all this IS the PGA.
