Assuming there is no dirt involved, I have great admiration for Ferrer. He for sure maximized the output under the limitations of his talent. Not many people can perform to the maximum level their talent allows. Incidentally, Ferrer has won most grand slam matches among the currently active players who have never won a slam. Second in this category is Birdman.
Nice little trivia bit, GSM! I do think that Ferrer makes a great contrast to some of the brattier younger ones that have made news of late, not least of which Tomic. And here's where I don't buy
@Front242's claim that he's dirty: if you have the money, and you're lazy and just want to make money, as Tomic has outrightly claimed, why not buy the pinch? On the other hand, if you're Ferrer, and you're getting the illegal bump, why work so hard? One of the usual commies says he'll go out and run 6 miles after a match. And I don't think that any PED buys you the mental commitment to a match that Ferrer has had. He's also made a lot of his serve for a smaller guy, and has a very effective inside-out FH. That comes from hard work. As you say, he's made the maximum out of what he's got.
