Yup and I have a hard time convincing myself that Nadal playing his absolute best would fail to win a single set from Federer at USO 2004. Federer dropped sets to 19 year old Baghdatis and barely pulled out a win against Agassi that year. Just because Federer fed Hewitt two bagels, does not mean Nadal will get the same treatment in a match. Once Federer hit his prime, Hewitt's game stopped bothering him all together. He would just hit right through Lleyton. More powerful baseliners like Agassi/Nadal don't have trouble generating their own pace and have better success keeping up with Federer from the baseline.
