I fancy an in shape and focused Olivares quite brutally at either weight. If he comes in underdone though..I could see him having a ton of trouble at feather and very likely losing.
Pac just wasnt the fighter he is now when he fought at those lower weights. Olivares though was a brutal puncher and would have gone close to stopping Pac imo.
Olivares at Bantam. Probably Pac at 126 (depending on which Olivares shows up, I'd say the version that fought arguello would have enough nuance and power to get rid of Pac)
Olivares would brutally destroy pacquaio at bantamweight, it wouldn't last more than 4 or 5 rounds. At featherweight however its much closer, the olivares we seen there the majority of the time would lose, most likely by KO, at his best there he may be able to outbox manny, i don't see him stopping him though as manny chin improved as he went up in weight (or when he was cutting down to an unhealthy amount like at fly) but it would be a difficult fight for him. I'd probably favour olivares at his absolute best there but i ain't sure about that
