In 2005 the following clay court specialists stopped playing -Keurten - 3 times RG champ, at age 26 had to basically retire because of his hip injury. Even with his injury he knocked Federer out of the French Open in 2005, Federer was obviously at his very best. He had a very similar playing style to Soderling, except with a better backhand and far better movement. -Coria - won 5 clay court tournaments in a row 2004. had a mental breakdown and couldn't serve at all after 2005. Had one of the most incredible matches in claycourt history with Nadal in the Rome final in 2005. He too stopped playing that year. -Gaudio - went 42-8 on clay in 2005, beat and Bagelled Nadal that year as defending French open champion (as all the great backhands have: Nalbandian, Djokovic etc). Like Coria he had a mental breakdown and stopped playing. Ferrero - Got the chickenpox in 2005, came back and his forehand had disappeared. Still hasn't recovered his forehand, he ceased to be a top 10 player after that. Moya - got old/backhand disintegrated. Today's so called 'clay court specialists' like Tommy Robredo, David Ferrer and Almagro aren't even as good on clay as Sampras was. Nadal had literally no competition until Djokovic came into his own this year. Keurten in particular would have been a HUGE problem for Nadal with his incredible backhand, he would have dominated off that wing the same as Nalbandian, Djokovic and Davydenko have. The same with Gaudio. Coria was just incredible and would have had his wins too. Can we really say Nadal would have 6 RG titles if every single clay court specialist hadn't been struck down at the same time?
