O god no not again.The commentators were correct in saying Federer's 2009 rise was related to Nadal's 2009 slump/absence. Federer's rise wouldn't have happened if Nadal was in usual condition at Roland Garros, because it would have been another Federer-Nadal final with Nadal winning. And at Wimbledon we saw Federer play very poorly off the ground and only his serve saving him. If that had been Nadal in the final instead of Roddick there is a good chance Nadal would have dominated the rallies (based on Federer's groundstroke form). So I do think Federer would have lost both RG and Wimbledon if Nadal played RG in normal condition and if Nadal played Wimbledon. RG especially, considering Federer played very messy tennis, he didn't even play well compared to past years.
You mean the normal Synthetic condition, right? Just what is Nadal's "normal" condition?
