I'd be rooting for Fed had Agassi beaten him in the 05 US Open Final (Agassi was up a break in that 3rd set at 4-2, one set a piece) and Roddick gotten his much deserved win in the 09 Wimby final (damn you high backhand in 2nd set tie break or those two big serves Fed hit down 15-40 in the 5th set).
But alas, it didn't happen that way so go Djokovic. 17 is more than enough.
