It doesn't matter how much the others have not won, that is not the point we are talking about here, you mentioned how Fed hits the ball not how much He won.
The reason why Fed won what he did is not only about hitting the ball, it has a lot more to do than that, such as conditioning, strategy, mental toughness, movement, footwork and so forth, and hitting the ball one more variable to this whole equation.
Gasquet, Wawrinka, Almagro can hit backhands against Nadal's forehand all day long, they can also hit winners with their BH from anywhere in the court, Fed doesn't even come close, not even an argument.
Using your point of view then these guys should have won more than Fed, because their BH are far better than Fed's using bigger rackets, and why they have not??
Because of all the other aspects involved in, that makes Fed who He is, have you thought if Fed had a backhand like Gasquet or Wawrinka's??
By now He would've had 40 majors.
This is my last statement on this issue.
You believe in what you want to believe, I am not gonna cahnge your point of view neither you are changing mine.
