I'm really not sure who is the best athlete I've ever seen on a tennis court. I'd have to say it'd be either Sampras, Nadal, or Federer. I would put Sampras and Nadal, both, ahead of Federer but then it's a wash between those two. Pat Etcheberry, fitness trainer extraordinaire, reported that Sampras trained for some time, side-by-side, with Charles Woodson before the NFL combines that were coming up for Woodson. Etcheberry reported that Sampras was neck-and-neck with Woodson. Here's an excerpt: Here's the link: http://www.sportsmediainc.com/tennisweek/index.cfm?func=showarticle&newsid=13993&bannerregion= Nadal's athletic prowess is obvious and well-documented--but I really wonder who the better athlete is? Nadal or Sampras? Are there some of you who think Federer is a better athlete than these two? Maybe another player? Pat McEnroe keeps talking about how to play top-level tennis these days you have to be a top athlete. Is that true? What about Nalbandian? Is that a fair thing to say about David? So I guess I'm asking two things: 1.) Who was the best athlete you've ever seen on a tennis court? 2.) Do/Did you have to be a great athlete, or one of the best athletes, to be one of top-ranked players on tour today or even in the past?
