Klitschko's beating of Danny Williams was probably the most humorous dismantling he had. The way Vitali counter-punched him repeatedly was almost video game-esque. I think Kostya Tszyu's methodical performance against Miguel Angel Gonzalez qualifies. Timothy Bradley against Brandon Rios. Golovkin vs. Lemiuex. It wasn't a stoppage but Wright systematically beat Trinidad. Same with Kessler-Andrade.
Petrolle-Battalino Basilio- Tony DeMarco 1 and 2 Virgil Akins-Vince Martinez Joe Brown- Wallace Bud Smith 3 Baer -Schmeling Walker-Milligan Gavilan-Bratton 3 Gavilan-Davey Jimmy Carter-Tommy Collins
Chango Carmona v Mando Ramos (probably more systematic slaughter) Rodolfo Gonzalez v Chango Carmona (A methodical and comprehensive beating) Ruben Olivares v Zensuke Utagawa (Slow and precisely took Utagawa apart piece by piece)
Roberto Duran vs DeJesus , Duran just wouldn't stop coming. But his beating of Moore may be the gold standard
Hagler v Minter Hagler v Sibson Duran v Moore Fury v Wilder ll Honeyghan v Curry Calzaghe v Lacy Tyson v Berbick, Holmes, Spinks, Frazier ( too many too mention ! )
hopkins vs trinidad holyfield vs tyson pac vs oscar toney vs jirov mab vs hamed margachito vs miguel cotto pac vs margachito mosley vs margarito chris byrd vs jimmy thunder
man, coopers power was no joke. Those jabs were opening his head like a pez dispenser. His hooks were short and compact. Good stuff
I'll give some love too J.Frazier, his fights against Mathis Sr, and Terrell. Brutal and beautiful at the same time. Whitaker vs Ramirez arguably both fights, Whitaker may not have had great power, but he was a Picasso against Ramirez both fights. Nelson vs Fenech #2. Nelson said he was weakened in the 1st fight by malaria. That 2nd fight proved he may have been telling the truth. Sanchez vs Gomez . Sanchez vs Lopez,,,,, twice. Pryor vs Cervantes. Overwhelming. Ibeabuchi vs Byrd. J. Louis said " He can run but he can't hide". Someone should've told Byrd that before he faced Ibeabuchi.
Jess Willard Beat the soul out of Jack Johnson as would be expected of a man who made his career fighting super middleweights.
Rahman vs Meehan. Meehan's punches had no effect at all on Rahman, while Rahman's had plenty on Meehan.
Calzaghe vs Lacy Hopkins vs Trinidad Hopkins vs Pavlik Pacquiao vs ODLH Pacquiao vs Algeri Sanchez vs Little Red I Foreman vs Fraizer
I would put both Bhop vs Echols I and II in here as well. Echols had shot after shot just pinging off his head. In the first fight the last 6 rounds were a methodical beatdown. The second fight was very lop sided. Echols never once parried or ducked in 22 rounds he just comes forward with his chin in the air. His defense consisted of just his chin, clean shots right on the button. He resets and the same thing happens again - rinse and repeat. Echols was one tough SOB in those fights but even his chin and durability had limits.
