Floyd has proven that Madaina's style is ineffective against him. However, the same style is ineffective against Pac as well, but at least there'd be some fireworks before Madaina took his count.:think
This. Mayweather would pick Maidana apart. Pacquiao would too but in a more offensive manner causing serious damage to Maidana.
They both KO Maidana, but the Pac fight would be a lot more fun and action packed. Floyd will just pop shot him in a snooze fest.
Maidana will actually come after Mayweather, and has some defensive issue. It could be a one sided fight but it wouldn't be a snooze fest.
Both fights would be good. Maidana/Mayweather is better as the combined stature of both are higher than Maidana/Pacquiao right now.
