What about it? How would Johnny Mac - a lefty with a good serving game - in his prime have done against the Fed? I don't think he could have unnerved Fed, since for the most part the Fed appears to keep his cool and goes about his business no matter what (though he did slam his racquet down against Nadal). I might give the edge to the Mac. But by the time Fed gets done with his career, he may make me change my mind.
