Delpo also rolled over Nadal that year, ok?If someone like Delpo starts taking breaks off without being injured than I think it will open the floodgates for other players in their 20s to start doing the same IMO. By your criteria even Cilic has paid his dues because he won 1 slam beating Fed along the way. I think moves like this could precipitate an acceleration of the BO3 standard set lengths devolving to shorter sets and that wouldn't be well received by anyone here.
And 2009 Fed > 2014 Fed (who played Edberg tennis because he was weak off both wings).
In the past it was common...for Spaniard and Latin claycourters to skip grass.Players are now starting to collectively skip the entire clay season. If that’s not a sign that the season is too demanding, I don’t know what is. Clay is an essential part of tennis, historically speaking as well. I know North Americans aren’t too familiar with it but I believe it’s the most popular surface in Europe and South America. It would be terrible if people would start seeing it as some kind of bonus surface instead of an important core surface of the ATP tour.
