It'd have been a war, but LaMotta would've gotten the better of it for sure. LaMotta was much greater than Chavez Jr, but styles make fights, and they'd have had a great fight.
Basilio vs Rios @ 147 great fight but Basilio too strong and Rios gets stopped Layne vs Adamek @ heavy I like Layne in this one but a close rough battle LaMotta vs Chavez Jr @ 160 Lamotta all the way Tiger vs Cloud @ 175 Tiger Marciano vs Arreola Marciano by KO
Some others that'd be barn burners Tiger vs Martinez Graziano vs Margarito Fullmer vs Benn Zale vs GGG Ketchel vs GGG Armstrong vs Pacquiao Basillio vs Cotto There's a lot more as well. But there's more competitive old school vs old school match ups imo.
Would it? Very doubtful it would be a brutal war beyond 4-5 rds if Duran is physically and mentally ready to fight...
Basilio UD Layne stoppage LaMotta stoppage or RTD Tiger wide UD or stoppage Marciano decapitation Terrible matches, you're comparing ATGs with mid tiers from this era. My old vs modern matches: LaMotta vs GGG (15 rounds) Mayweather vs Battling Nelson (45 rounds) Beterbiev vs Marciano (15) Gassiev vs Marciano (15) AJ vs Marciano (15) Wilde vs Inoue Wilde vs 5 star grilled chicken Antuofermo vs Hurd (15)
Wow ..crazy that all five of those guys were relevant just a half-dozen years ago but now are relics.
