Is he Nadal 2.0 playing at U.S. Open ?

He hasn't really been tested with a strong US Open contender (not that there is anyone besides Federer who has won it), but a typical strong US open specialist - Big flat serve, big flat forehands and backhands, agressive play, etc. like Federer, Djokovic, even Rod, Fish, or a Marat Safin type. It will be interesting to see how he adapts to those types once he inevitably runs into them. If he surprises like he as done on other non clay surfaces, that will be interesting.
