How come Nadal is one of the few breaking down compared to the rest of the tour????? Could it be because the rest of the tour actually knows how to schedule their tournaments so that they don't get overworked??? Look at the rest of the top 10. Roddick was out for a few tourneys due to a bad back. Davydenko missed a few. But Murray, DelPotro, Fed, Djokovic, Simon, Verdasco, and Gonzalez are relatively injury free, with minor pullouts because they went deep into a tourney the week before. How many more tourneys has Nadal played than these other players. Yes, he's played more matches, but whose fault is that??? It isn't the court or the schedule, it is his own schedule making and the fact that his knees are injury prone. This isn't the 1st time, nor will it be the last time, that Nadal has to pull out of tourneys because of his knees.
