First off, I'm not calling any of these guys pushers. Fan boys can relax.... one would hope. Here's my list so far: Nadal (just hit hordes of topspin at the opponent's backhand, probably gets most of his winners coming off a defensive reaction) Federer (those frequent slice backhand returns of serve border on pusher-like behavior) Simon (another grinder, likes to hit paceless balls at aggressive baseliners) Murray (chases everything down, mixes in slices and various pace shots, only goes for it when the odds are absolutely in his favor) Roddick (even his new coach has criticized him for just being content to keep his groundies in play) Santoro (do I really need to explain?) Stepanek (yes he has an all-around game, but he enjoys hitting paceless balls off the forehand) Monfils (built like a beast, but is at home being 15 feet behind the baseline, hits slow-medium pace on many of his groundies) Gonzalez (slicing like Benihana off the backhand) EDIT: Due to counter-arguments from posters, Davydenko and Djokovic are off the list. Robredo and Lopez were mentioned. If someone can make an argument for or against, feel free to chime.
