Is it just me or has the best shot in tennis lost some zip? He can still crank winners but it seems lately when he goes for the lines he misses, so his normal forehand rally shot is not nearly as powerful, and his movement, anticipation and defense keep him in the point. He's relying a lot more on placement and angles than power, and even when he gets in a good position is not able to force an error as much as he used to. On clay thats a very dicey proposition against Nadal. Its not just clay - compare the forehands he hit in 04/05/06 to the way he played the USO in 07, I don't see the same end-points-at-will shot. Combined with his newly discovered hobby of losing serve when serving for the set, it has proven costly.
