I would pick the Pacquiao that diced up Cotto to beat the drunk Benitez that struggled against Donald's older brother Bruce
I think a peak Pacquiao (DLH/Cotto/Clottey) might have too much combined speed and firepower for El Radar to elude.
Nah, Morales and Floyd used their length to keep Manny resetting. I think Benitez's defence, footwork and 1-2, as well as height and reach is too much Pacquiao. Benitez should shut Pacquiao's offensive down, and keep himself out of harm's way.
Pacquiao hadn't yet developed his peak skillset at the time he lost to Morales, and his footspeed noticeably slowed down post-Margarito. Morales wasn't able to replicate his earlier success against Pac once Pac reached the height of his powers. I think an MM using Pac from '06-10 has a potentially different outcome than Pac from outside that time frame.
