The obvious one is Locche vs Fuji so I'll just get it right out of the way. Zapata vs Penalosa is the one I'll nominate. Freakish movement and reflexes from Zapata.
Nunn-Tate is up there. Nunn stood directly in front of Tate, lit him up from all angles, and Tate couldn't lay a glove on him. In a similar performance, Pedroza vs Ford also comes to mind.
Miguel Canto vs Antonio Avelar Winky Wright vs Felix Trinidad Miguel Lora vs Daniel Zaragoza Gilberto Román vs Sugar Baby Rojas 2 Sumbu Kalambay vs Mike McCallum 1
Sal Sanchez went into slickster mode in the Danny Lopez rematch. It was a great defensive performance but Lopez wasn't exactly a prime Hearns in the offensive department.
Whether it's one of the absolute best or not, Toney-Barkley immediately came to mind. Beautiful defence without fighting 'defensively' at all.
Whitaker against De La Hoya. His offense was lacking, but defense was brilliant, especially given the caliber of opponent and Whitaker being on the downside.
I've always thought Wright vs Tito was a damn fine showing of a high guard. Hopkins vs Tito too, actually. Poor Tito lmao
Jones-Toney has gotta be up there. Also, a VERY slept on and underrated one -- Monzon vs Griffith 1. Griffith couldn't lay a glove on Monzon.
Hopkins Vs Jones I was good. Jones was knocking guys out. Not so Hopkins. Hopkins also got his own shots off.
Bernard Hopkins’ performance against Kelly Pavlik and Antonio Tarver was masterful stuff. Marlon Starling vs Lloyd Honeyghan Guillermo Rigondeaux vs Nonito Donaire Anselmo Moreno vs Vic Darchinyan Chris Byrd vs David Tua
Albeit Winky greatly aided by Tito responding to a southpaw like he was reading an instruction manual upside down
