How would this fight have gone? Most of the stuff i've read have been Monzon being able to survive and pick off the attacking Marvin to win a UD This how you see it?
Monzon takes a UD here. If Hagler pressures Monzon would pick him apart to win a close fight but would have taken some punishment when Hagler manages to close him down and get on the inside. Monzon would most likely win enough rounds to take a UD. If Hagler boxes then he looses a one sided box off.
Monzon by decision. Hagler had rep, Monzon was meaner in ring though. Hit harder also, better inside fighter too, and extremely strong.
Monzon was so effective as a champion because he could always keep opponents at bay with the trombone jab, and tie them up when they got too close. Valdez and Briscoe pushed him, but ultimately lacked the skill to overcome. Hagler on the other hand is very well-rounded. He could adjust and mix cuteness with brutality, whatever the situation called for. I envision Hagler slipping under Monzon's slow jab, and then countering to the body. Hagler slowly chips away, and Monzon tires late. Hagler by UD or TKO in rounds 14-15, IMHO.
Arguing emphatically either way is a fool's errand. However, I do take Monzon in this one. Regarding his jab, it was much like that of our beloved Wlad, he would kind of paw in slow motion trying to create opening, then when needed slam it in with much more speed. So, labeling it "slow" is rather deceptive. He alternated the speed of it as needed, somewhat like a baseball pitcher throwing fastballs and change-ups. It was a very effective weapon. I see Monzon ultimately controlling the pace of more rounds than Hagler, getting the fight into his rhythm, landing more blows and not fading down the stretch, taking a UD.
I am not sure about that. Hagler's ring generalship was nowhere that of Monzon's, and one of his problem was indeed the inability to adjust well--otherwise he would have beaten Leonard and blown out Duran, as both were over-matched when they met. Monzon with his upright style and pumping that heavy jab is a very bad style match-up for Hagler, who really needs to be a lot more aggressive than his habit to even have a chance to win v. Monzon. (Moreover, unlike Tommy with that "weak chin"--Marvin's own words--Monzon wouldn't wilt once Hagler touched him inside.)
Hagler could take away excellent jabs really well, just look at Hearns/Minter fights, he could parry and slip inside while using his own jab on his way in, that's why he was so good at closing the gap against taller men. At mid-range and on the inside Haglers better speed, shorter punches and combinations would dominate that range. Monzon would have be forced to use movement to keep range, at the range Monzon gets the better of it but Hagler's constant parrying and intelligent pressure would see him closing the gap. Hagler's bodypunching and greater strength would be a significant factor. It would be a battle of movement, of pace and that means it boils down to who had the greater stamina to control the range?? I'd go with Hagler in the stamina department, it would be a fascinating contest, a close one, but I think Hagler had more in the bank to impose his will and Monzon would finally be punished for his smoking
You make some good points, but Hearns fought Hagler flat-footed (whether due to machismo or mobility problems due to "massage") until he was spent and could only throw flickering punches anyways, and I don't feel Minter really represents the problems Monzon would for a variety of reasons. Also, Hagler may have been stronger, but Monzon, despite his thin build, wasn't weak; and Hagler was also not immune to getting pushed around (which I think is all besides the point, because I think Hagler will get suckered into fighting from Monzon's distance anyways). Finally, I wonder if you are over-rating Hagler's stamina. He tended to flag down (despite his legendary training regimen) even against guys like Antuofermo.
