Eusebio by real close UD. As long as it is held in neutral territory.
Robinson by 3rd round ko.
Quite a few, Alex Ramos and Milton McCrory come to mind, as well as Jeff Chandler, though to Jeff's credit, didn't try to comeback, or remain...
After seeing Mitch Green dispose of him in 1 round in the 1977 NYGG, I didn't consider Guy that highly.
Spinks would win a close decision. His awkwardness would be a key factor.
Pedroza-Taylor. Murata-Pintor Boza Edwards-Elizondo.
Muhammad Ali, Larry Holmes, and Riddick Bowe of the late 92 period.
In a 15 rounder, Victor would beat Bernard by a strong UD.
Even though he wouldn't be able to beat him, Randy Shields could have given Floyd fits.
Watch some of his earlier fights. Then compare them to Post-Rosario. It's really sad.
Jimmy by SD. Don't see him having major advantages over Michael, and depending on the timing, politics could get involved.
Most of those guys would take Marvin, possibly Machen he does beat.
I think Muhammad could do the trick against Gerry in 7, if he really wanted to.
No offense, but after Rosario, Hector was never quite the same fighter that he was during the early days. Yeah, he won a few more titles, but...
Unfortunately, that would me more of Mike kissing Kevin on the mouth. Really unnerving.
