I disagree that mental strength is as big as youre making it out to be. How do you decide who has the best mental strength? just sort by the ATP ranking? what about that guy that played with appendicitis? somehow i dont see him making the top 10 any time soon.
Lol? You can't be serious. The guy that had appendicitis didn't play a top player now, so really stupid comparison. Fact is players are better than each other in the top 200 because of stronger mental strength. Roger, Rafa and Novak are at the top because they are the best mentally day in and day out against everyone else. Yes, they lose to lower rank players here and there, but that doesn't mean they aren't mentally stronger in general. They clearly don't hit the ball the biggest, they aren't the fastest players on the tour, they don't have the biggest or best serves, etc. In fact for many of their attributes, you can find plenty of other players in the top 200 with just as good or better aspects.
Again, the fact that you didn't answer my question of why Murray isn't in the mix with those 3 I mentioned. Sure, people complain about his forehand, but it is good enough. It is entirely mental for him to continue to play the right shots and actually connect with the ball on an important point. Taking PEDs aren't going to make you focus and come up with a first serve on a break point down.
