This is the opposite of the "name something good about the players you dislike the most." I'm really interested in some posters' thoughts in particular.
Roddick -- can be a bit of a jerk when he's losing and a bit of a jerk when he's winning
Gasquet -- should man up and grow a pair
Nadal -- should really be called out more on the time he takes between serves. He's not tired so that's not an excuse
Korolev -- should fire his dad and get a real coach
Blake -- he's not really as nice in person as he seems
