I think Pac Man hasnt recieved much of a beating throughout his career
Yes he has. His losses come from KO/TKO, look how he ended up in both fights vs JMM (both being questionable decisions), his clear lose vs EM, etc.
the last time ive seen pac being punched in the body pac just went berserk and kod the opponent
I remember something different. When he fought JMM 2, he got hit in the body a couple of times but it was specially on round 8 or 9 where he clearly looked hurt and tired.
