At this stage I would much rather Manny not fight anymore. As bittersweet as it would be to see him retire for good, I would prefer that to seeing him run the risk of getting hurt. But, of course Manny has stated that he intends to fight on taking it one fight at a time.
This would be a great ending to a legendary career:
Rematch Barrios to win the WBC World Title
Fight Rolly to win the WBA World Title and unify the WBA/WBC titles
Rematch Floyd in a massive unification welterweight showdown.
Again, wishful thinking and I understand this is boxing and it's an unforgiving sport. But, if anyone can achieve such a feat, it's Manny Pacquiao.
