I think to some degree the same thing has happened in American tennis as in American golf. Players aren't as hungry anymore, the money has overwhelmed the sport. You can be a good but not great pro and between prize winnings, appearance fees, etc..., you can make pretty incredible money. And the money the top guys make? It's a whole different era now than it was 30 years ago. I've got a book with a picture of McEnroe being presented the large cardboard check after winning the US Open, I think it's for $60,000.
And the way we train these kids, they are so catered to, so pampered, so enabled.
