Pacquaio is around 5'7, 140lbs or so and hits hard for his size. But Andre the Giant in his prime was 7' tall and about 450lbs. If both guys threw a punch, whose punch would cause more damage?
I doubt Andre could land a punch on anybody with decent reflexes but an Andre the Giant slap would have more force on it than a Pacquiao punch.
Andre the giant was a monster. I doubt there were too many people in history who coulda fucked with him
Watch Andre in this video against Japanese wrestlers. Watch from the seventeenth minute. I think he really hurt the guy. He dropped the guy on his head. http://www.youtube.com/watch?v=NUs1R6O2Eeg
Andre could hit with incredible force without even looking like a good punch..just too much weight behind it
