5. Tennis has become extremely demanding physically, so its obvious that a lot can be gained.
Number 5 is true and you know that Roger led the way with that right? So if all we need is hearsay, how would you feel if I told you I know some former pros and trainers who think that Roger is doping because no one can do X Y and Z like he does and they figure he must be doping.
Somehow I think your enthusiasm for guilty until proven innocent would subside very quickly.
Somehow I thought you were serious with your posts until I read this post. Turned out you've been trolling all along.
Have you actually seen the way RF playing?
Have you actually seen the way Nadal playing?
Have you actually seen the way Djoker playing?
Have you actually seen the way Ferrer playing?
If you weren't so blind you would see that he is in the same boat with all successful tennis players today.
And if you weren't so blind, you would have known that RF would have been a lot more successful had the courts not slowed down.
