why, because Nadal lost to a guy barely in the top 100? so let me get this straight...when fed routinely owned slam winners like agassi, roddick, hewitt, djoker( yes, he still owned djoker after AO 2008 til this year), and safin, its a weak era. but nadal loosing to a guy playing out of his mind in the second round proves its a strong era? maybe it proves( especially after losing to kohlschreiber in halle) that rafa was still in clay mode and not ready for grass tennis. and that he got outplayed today.
