122: Fenech TKO10 126: Fenech UD12 130: Pacquiao KO4 135: Pacquiao KO1 Pac had massive issues with Hussein at 122, who fought like a homeless man's version of Fenech. In his late years, he was massive troubled by Horn, who also fought like a homeless man's version of Fenech. If you pair that with the issues he had at 122 w Sanchez and his dirty fighting, I think it's pretty easy to pick Jeff at 122lbs, by late stoppage at that. Pac has his power, was more comfortable and skilled at FW, which is where this match-up is most interesting IMO. I think it's very possible that Fenech walking into Pacquiao's bombs results in him getting KTFO'd. Jeff's chin was brilliant, but it wasn't impenetrable. He was briefly hurt by Callejas and Nelson, both early in the fight. Is Pac comes out like he did vs Marquez, it could be over quick. If not, I think Fenech mauls him to a win. Obviously Pacquiao obliterates Jeff anywhere above 126, and it only gets worse as you go up.
I suspect Pac might be too much for Jeff even at 122-126. His offense is just too devastating for a guy to be walking in on it all night. Jeff has his best chance at 122.
