Yes, fluidity. This is what (should have) lost him both fights. Twelve rounds gave him great familiarity with Pac's rhythm. Is it so complex though that better fighters than Marquez wouldn't figure it out sooner, and stay on their feet in the process? Debatable. Fluidity. What? Anything "might" happen. All we can talk about in any mythical H2H are probabilities. A proven great technician, with a proven great chin, fighting in his natural division against someone smaller who has problems with boxers, probably wins. What are reasonable ones?
