The Macho that fought Chavez Sr. I think Paul wins this in a very exciting split decision. With a lot of speed and exciting combinations.
I'd have Macho-time hurting Paulie and getting the TKO win in the later rounds. Good boxing match though.
PM has tons of skill, but he just doesn't have the power to compete with the cream of the crop. Similar skill levels, but HC is a tid bit faster, and has much more power. They would land a similar amount of punches but PM would get hurt and HC wont feel a thing. I could even be underrating HC here, especially considering the era he fought in.
We're talking the 1992 Camacho though. You're right about Paul's lack of power but this was a relatively washed up Macho, a macho that would break mentally, especially against a guy with similar speed, that would keep coming. I think Paul could break him down, and win but get robbed in a close fight.
