2. Serena Williams: OK, she comes in hobbling, complaining and winless since Key Biscayne in early April. (Not tournament winless; match winless.) She lost in an undignified manner in Paris in 2008. Don't care. Logic and conventional barometers go out the window when she's playing in a Slam. Having been burned too many times in the past, how do you not pick her to win every Slam she enters?
