does "coming back from severe injury that kept him an eternity out of the game" sound important?
does the fact he won him twice pre-injury sound important?
stats are numbers, which make sense when analyzed correctly
in a QF of AO Del Potro would be favorite against Ferrer and i believe he would win.
QF means he passed 4 rounds and is in solid enough form, while his style is one to blow Ferrer off the court, that's all.
in a QF against ferrer, ferrer would be the favourite imo. You can't only look at form. Roger is a perfect example of that. In 2009 and 2012 AO's for excample Roger was playing very well, high level but when he plays nadal we know who has the advantage - matchup issues.
Also, they played 3 times in 2012. Del potro gave a lot of trouble to Roger as early as Dubai. Ferrer beat del potro in the WTF, that's end of last year when del potro had already beaten Roger in basel, played great in the olympics defeating djokovic,....
Let's hope they meet in the AO, preferably quarters.
And of course data has to be analysed correctly. If they had only met on clay for example that would tell us little about a match on HC.
