It was Tiger's own hubris that led to his downfall, his arrogance that led to his misdoings... he seemed to believe he was above it all and took what he wanted and thought he could get away with.
If anything, it was the fact that he finally appeared to show some humility recognizing the fall that followed from his actions. The physical and psychological tole it had on him led to his decline. It doesn't matter how it get's reported there are always going to be a variety of impressions regarding him. He has made great strides, but he was/is simply too talented and gifted to not expect him to eventually get there.
Whether his shortcomings are ever fully forgiven or cast a shadow on him personally, it is hard to say, but his skill on the course is very difficult to dispute.
His peers admire his accomplishments but they also appreciate the impact it has had on their own financial growth as well. Tiger did in fact play a major role in bringing large amounts of money into the game and they are now almost always playing for million dollar purses every week... of course they value Tiger because they know what and how it benefits them as well.
Of course Jack and Arnie and many others would have had the same if not more of an impact if they had been surrounded by the "marketing" and "economical influence" during their era... many other factors also played a role in allowing Tiger to be the catalyst including growing money and endorsements in sports as a whole, the economy, corporate interests, etc...
It may have even led to the growth of online games for all we know... Afterall, rumor is some people even take up video golf and pay what amounts to $10 for a sleeve of 3 limited used golf balls. Someone has to making something off of that as well. Shoot a couple guys even earned a trip to Atlanta to play heads up! Amazing huh?
Somehow, I think the game is doing pretty good and love him or hate him... Tiger is definitely in the discussion as playing a role in that.
