re: Is Rafael Nadal done?

I was kind of bummed as a kid when Johnny Mac and some of the Swedes I liked like Edberg and Wilander faded, but along came Agassi (and Sampras). Then, I honestly thought I wouldn't watch the sport much when Agassi retired, but Fed, Nadal, Djoker, and Murray to some extent have taken it to insane heights. We may be ending the golden age of tennis and just end up having guys who win a major here or there like Roddick and Hewitt, but I suspect someone will come along and dominate.
