One of the problems with the PGA tour is that they do not market any of their best players, and let other sponsers do it. People know Phil and Tiger, maybe even Sergio, but did people know that Goosen was ranked 9 in the World before the tourney? Paired with Els who is #2? This is one of the best players in the game, and he is probably unknown to the casual fan. Vijay Singh people probably know, but David Toms? Jeff Maggert?
The PGA game has come to depend on Tiger, and it worked when he was in it every Sunday for a few years straight. Now, with Tiger out of the hunt the last two years, viewers see a guy like Goosen, who is a pretty amazing player, and think he is some nobody.
The PGA had Goosen and Els in the final group, with Mickelson, Funk, Maruyama and others right behind. The best players were on in it on the final day (minus Tiger), and I doubt they did very good ratings.
