I see the Monzon fight as a very close matchup, Monzon was not Roldan and Hagler was better than Briscoe, I think this fight boils down to battle of the wills and who forces who to fight there fight ,Hagler from the inside and Monzon from the outside,Close Decision....SSR, a fresh version could box the ears off of Hagler but could also hit harder than anyone Hagler faced...SSR UD or TKO.....Walker was the bodypunching Middleweight and as tough as a Bulldog, Hagler tries to out box the body punching BullDOG but Walker Puts too much pressure on Hagler for a Close hardfought UD..... GREB outhustles Hagler for a Clear UD
The guys he faded against. A couple came home better I was of course talking comparatively. Hagler came home better vs Duran but Duran was outgunned in reality, not a genuine middleweight and he was always going to get gassed here and there - which he did.
Most would probably lose to him. But if Colbert can give Hagler fits, then Monzon, Robinson, maybe even Griffin.
