The rest of the field has caught up, there won’t be a dominant player, maybe ever again. Just look how many good players there are now outside of the US. In fact, it may very well be Tiger’s legacy that he made the game more popular in the rest of the world, and we’re now seeing the emergence of those players.
Very true about the rest of the field. Tiger set a new precedent and we now see a slew of very athletic players..and from all over the world. I am not so sure we won’t see dominant players again, because that is something that only happens once in a great while anyway. I suspect if we do, it will be for shorter windows of a few years, rather than the two decades at a time we saw from Jack, Tiger and others before them. It is rare to have a single person so dominant anyway, and now the talent level is becoming that much higher.
That said, I still suspect we’ll see at some point another run from Tiger over a few years. Not like when he was younger, but I suspect he’ll win at least one or two majors in a year at least one more time. I still think he’ll get 19, but much less certain than two years ago.
Although time will tell, I think that may be overstating things. Outside of South Korea--and then only on the ladies' tour--the same countries that have historically produced great golfers are still the countries that are producing great golfers: the United States and Great Britain and its former colonies. There are a few oddities here and there, but by and large, the players that win majors are from those countries.
