I study image repair in one of my PR classes. Some of him has to be sincere, simply because he and his wife are trying to get back together. Say they do stay together; Tiger can never cheat on her again, because if he is caught, his image will be irreparably damaged. America is forgiving, but not twice. So if he really wanted to just keep getting laid without the threat of his image crashing down for good, he would get divorced and there would be no issue (sorta like Michael Jordan).

I highly doubt that Arnie is the reason that golf purses increased 300 percent from 1997-2007. I love Arnie, but he is not the reason. The reason was that there was a guy that was a minority dominating the hell out of his sport. The turning point was when Nike signed with Tiger and created Nike Golf, which made golf much more mainstream. Where golf was an old person's sport (even during Arnie's time), it was being taken over by a youth revolution. The fact that his popularity spanned all demographics is just astounding.
Tiger woods had the highest public approval rating of any public figure (and I mean all people) in the history of the polling (somewhere near 90%). None of what I am talking about is due to Arnie. Arnie was fantastic, and advanced the game very well, but he hadn't played golf seriously in 20+ years. Most of the "Tiger" golf fans probably couldn't even tell you who he is or why he is famous, and it was these extra people that brought the big money and sponsors to golf (mainly Nike).
You are a smart engineer Zwick, but I think you need to take the blinders off of your Tiger hatred for one second to look at the PR, business, and economics of this situation. I know you are set in your ways about old golfers being superior, and I get that. I have that complex when it comes to music.
But this is simple econ: PGA Tour events in which Woods competed in 2003 attracted 65 percent higher ratings. Those numbers increased when Woods was in contention. 65% higher ratings= increase in demand for advertising. Once the opportunity cost of advertising on the tour became worth it (enough people were watching, because of Tiger--stat above), the advertising came pouring in, and new sponsors wanted in to a sport that was growing in popularity. The increased viewership brought on almost entirely by Tiger led directly to the huge increase in sponsors, and they had to compete with each other, raising the amount of money they were putting in the pool. The real value of every golfer went up due to Tiger, because of pure exposure, and the sponsors realized this value and upped the purses accordingly.
The telling stat is this- adjusted for inflation, the PGA tour purses grew almost 200% in ten years, a number eclipsed only by NASCAR and the value of the NCAA tournament.
I would love to see your argument with factual evidence on why Arnie increased the tournament purses so much from 97-2007. I am completely open to the idea, but I looked around for some arguments and couldn't find any. Not to say he couldn't have done what Tiger did had he come later too, TV and advertising money wasn't what it is now when he was playing, so it is actually very hard to make any real argument about his contributions.
