I don’t really get why Mayweather is suddenly being brought up. Yeah, he beat Pacman, but he’s been retired and there’s no sign he’s coming back.
After seeing Pacman’s fight with Barrios, you can tell he’s still tough to beat. Since he already tested himself against a taller opponent, maybe next time he can go against someone closer to his size, so we can see more of a toe-to-toe kind of fight, not the usual defensive style.
And honestly, no need to worry about his age. Manny’s already proven that age is just a number for him.
