They have got better Slams lately because JMDP had his progress derailed by wrist surgery. Even if we assume he'll never get back to what he was on a consistent basis, he's still far more likely of getting hot for a few matches and take a Slam than Ferrer, whose potential is far more limited. He's also more likely to do that than Tsonga and Berdych (although not by as much) everywhere but grass, especially on clay.
