Has manny fought anyone like Floyd Mayweather?

Has he ever faced a fast, technical, defensive minded fighter with a reach advantage? Diaz had a small reach advantage, but was not considered fast Marquez is a good technical fighter, but he had no physical advantages over Pacman Oscar had many physical advantages, but his defense was never considered great Personally I dont think either guy has seen anything like the other. A fast guy like Mayweather is missing on Manny's resume' and a fast guy like Pacman is missing on Floyds resume'. This fight makes so much sense on a cosmic level , that it would be a crime against nature if it didnt happen this year.
