in another word, does he fully utilize his lefty advantage? Nadal obviously not yet develope a big swinging serve to swing the opponent out on the ad court. Does he hit his FH with enough topspin that runaway from the opponent's BH? Some lefties utilize this born advantage more than some other lefties IMO, Mac, Goran, Korda, Muster, Rios, Vilas, Leconte. Arazi do Conners, Forget, Koubek, Lopez, Nieiemen don't thoughts?
