Pacquiao vs Marquez III

When Manny Pacquiao steps into the ring to fight Juan Manuel Marquez he is expected to put an end to perhaps his greatest rivalry with a dominant performance and that strikes me as a bit unfair to the fighters considering the history between these two all-time warriors.
Is this really based on style and skill? How much is based on things that may not mean a whole lot in a roped off square?
It seems to me that if there was room for separation between these two, we would have seen it over 24 rounds. I'm sure that if you gathered every scorecard in the world, totaled them up and averaged it out, you'd get a draw. Judges in training should have to score those fights as their final exam. I came up with two draws (113-113 and 114-114).
