The fearsome Mugabi who's very presence in the ring helped solidify the legacy of Hagler against the man at the opposite end of the spectrum in terms of pigmentation. Both bangers. What happens? What happens? I'll tell you what happens. Pavlik would knock his ass out in 3 rounds tops!
Mugabi was a helluva lot better than Miranda and Zertuchd and even they went past 7. So that prediction is retarded. However, yeah, I'd pick Kelly by late stoppage. Not a given though. If you're trying to fit an agenda, just know... Hagler woulda kicked the living shit outta Pavlik.
Yeah Hagler would have decisioned The Ghost but no where near as easily as Hopkins did it. Shiiiiiiiiiiiit
A prime Hagler would stop Pavlik. Most likely on cuts. Marv's jab would slice Kelly's face to ribbons.
Only guy I remember Hagler fighting that was anywhere near as tall as Pavlik was Hearns, who was a blown up Welterweight who had already been stopped at the lower weight. Pavlik would be by far the biggest man Hagler has fought. Bigger taller stronger. Hagler was a smaller man than Hopkins. Anyway, Marvin wins but stoppage is unlikely, cuts or otherwise.
Fully Obel, Willie Monroe and Bobby Watts were all 6 feet or taller. Hagler shreds the Ghost. Like X said Hagler's jab would do a number on Pavlik and he would tag him with power shots from both sides again and again. Ghost is a tough guy but he's not bringing anything to the table that Hagler hasn't seen.
Ghost brings the proud distinction of being whipped by his holy eminence, Hopkins. That, for Sly is enough to prove that Hagler couldn't POSSIBLY do a better job. Always an agenda. Always. Pavlik wouldn't be in the fight AT ALL. Hagler kicks his ass every single round until Kelly's corner has seen enough.
