There is a lot that I agree in
@Front242' post above -- but not all, or at least not at all times. Surface and context specific, the description is quite accurate, but there are moments/environments were thing are different. Actually this one of Nadal's best qualities , the precision which he can fine tune his game. Yes, it leads to longer matches, but in a lot of cases those are matches he had basically zero chance of losing it (and no, I am not saying that he wins like that
all the time). The physical effort for him maybe is not that big as it seems for us just looking at the time it took. Probably the mental effort to play outside his comfort zone would much larger. Most of us here play tennis and I guess we agree that a match that you can control is a match that, in a lot of ways, is not that demanding. So my point is that
some of his matches that take two and a half hours -- those that you could say that could finish in one and a half hour -- are not much more than a practice session effort wise.
Anyway, the point of the post was not that, but actually something I just though about Nadal's baseline shots while reading Front's post. Yes, I agree that Nadal is not an offensive player by nature, but as I guess Fiero just wrote somewhere, he
can be aggressive. Also, somewhere MikeOne was posting about how Nadal was
not a good counter puncher (and that was a good post, even if I do not agree with it entirely). With all that in mind, what occurred to me is that Nadal's rally shots depend heavily of the time he has to set it up. Duh! this is true for everyone, but is more radical in his case, as I hope I can argue.
Maybe is my selective memory, but think about when Nadal has absolutely zero time to think -- for example a very difficult running forehand -- in those situations
he is an excellent (and aggressive) counter puncher. In those situations his forehand is, nowadays and historically, right up there with the best. The "reaction" backhand a tad behind I think, but still quite good.
Other situation when his baseline shots are extremely good is when he has all the time in the world to set it up. In that case, the combination of power, spin and angle is often as deadly as gets. Very few players are more likely to hit a winner in those situations than he is. In that department the forehand is quite ahead of the backhand.
The moment that his baseline shots look more "pedestrian" is the middle ground -- when he does not have all the time in the world, but also does not need to merely react -- in other words, his bread and butter shots. In this case he will rarely hit a winner -- and that is the context I agree 100% with Front's analysis above. In this situation he is more defense oriented than the opposite (off course, that depends on the surface). Again, the fact that he can navigate that well between those different situations is one of his main qualities.
