Everyone has an off day. Fed broke Roddick what, 1 time in 38 return games in 2009? Does that mean he's not a great returner? No, he just had an off day and Roddick was serving incredibly well. And Fed was clearly a better returner at 27-going on-28 than he was at 19-going on-20.
If you're going to head that route by saying one match doesn't tell the whole story then there's no argument to say Agassi is better returner than Fed on grass. In that case Del Potro isn't > Nadal at the USO or Cash isn't > Lendl at Wimbledon because it's only one match. If you feel that way, fine. For me, one match is better than nothing, at least we have some data to look into.
