They should fight at 140 or 147. Lopez hasn't fought at either weight class, but he'd be the much bigger man on fight night.
Nah......Lopez would have to jump across 2 weight classes to fight Pacquiao at 147 so how could he be the much bigger man on fight night? This doesn't make sense.
Pac easy- would be a huge gulf in natural ability. Angles, timing, footwork, speed, IQ all in his favour.
From what I have seen thus far, I believe Pac wins a 116-112 decision. Lopez is big, has fast hands and hits hard, so Pac would have to be defensively responsible and not over commit to his offense. Truthfully, Lopez' ideal weight is likely at 140lbs. I suspect, however, that the thread starter would select Pac over anyone at the lower weights.
