I just been watching a few classic AA matches curtesty of the Tennis Nexus. He provides good quality mayches at reasonable prices ----end of plug! However, i noticed that AA tends to get aced a hell of a lot of time to be described as a great returner. In the 92 Wimbly final he was aced by Ivanisevic almost 40 times. At the 2000 semi match at the OZ open Pete aced AA over 40 times. Plus Joachim Johansson aced AA 50 times in the OZ open of 2005. These are but a few examples of the so called 'world's best returner being aced far too frequently. It appears that Agassi guesses on his returns and committs fully to a position and usually when he connects he makes a winning return or puts the server under pressure. However, this appears to be at the expense of making frequent returns. In comparison to say Henman who is also a good returner, but is not as famous as AA, Henman IMO makes more returns in play that neutralise the point as Federer appears to do by blocking the serve back. IMHO i find Henman and Federer's style to be more effective as they tend to be able to get a no. of returns back in, tend to reduce their opponents ace count and put more pressure on their opponent by forcing them to hit one more ball rather than AA;'s 'guess and hit approach'. Another factor lies in the fact that AA hits a with a two handed backhand that is fairly flat and this limits the variety of returns he can make. Thus, AA's returns on his Bh are all driven with one pace and minmal variety. Just my two cents.
