Tiger Woods made golf "cool" which drew in so many more people to golf. Golf needs nothing MORE than Tiger Woods to return and to be competitive.
No. Not even close. Golf participation has been dropping for more than a decade and most of that occurred during the time when Tiger was still relevant. Rounds played are down, golf travel is down, golf equipment sales are down, new players entering the sport are down, TV ratings are down, EVERY SINGLE ASPECT OF THE GAME IS DOWN. Tastes change. Golf is fairly expensive, takes a while to play and most importantly, it's a bitch to get good at it. The vast majority of the people who try it are going to suck and they're going to suck for a long time. That's always been a problem for golf, the attrition rate is high because people are 100% inept at the start and don't have the patience to try to get better. But there were always enough players who relished the challenge, who wanted to get good rather than admit that golf kicked their ass and that they failed utterly. They kept playing because is was hard, that was the appeal. To millenials with short attention spans raised on a lifetime of participation trophies golf is simply too hard. Most won't try it and almost all that do quit after a single round or two at most.
Tiger could win 10 tournaments next year and there would be a ratings bump, but a bump would be all. Viewership was declining while he was winning and it's going to keep declining in the long run. Tiger is not going to change that.
Seems like every week there's a "state of the forums" thread wondering why participation is down. That's the new world, forums are old-timers and the idiots use Facebook and Twitter. It's got to be fast, easy and have no learning curve to appeal to newcomers now. Golf will continue a downward trend and 50 years from now it will be a niche sport because there's nothing that's going to get new players into the game until attitudes change and it becomes cool to work hard at something to get good at it.
