Post prime signature wins

Bobby Chacon-Limon IV
Bobby Chacon-Boza Ii (although I felt Boza won)

 

Almost forgot Povetkin over Whyte

 

Considering the appalling accident and that he was past his prime and 20lbs north of where he won his 1st world title....and given its paz we are talking about in his career I think they were big wins....pazienza did some good box office in the duran wins and these....the sport could do with a pazienza now

 

Moore over Durelle
Mosley over Margarito
Toney over Jirov (or maybe Holyfield?)

 

Quarry-Lyle
Quarry-Shavers
Chuvalo-Quarry
Foreman-Moorer

 

Benn beating McClellan

 

Zora Folley's victory over Oscar Bonavena, 1965, George Chuvalo's knockout over Jerry Quarry in 1969.

 

of course, ali vs. spinks 2 was an important signature win, too - first 3 time heavyweight champ ever!

 

Joe Calzaghe vs Mikkel Kessler

 

Azumah Nelson vs Jeff Fenech

 

Carlos Monzon vs Rodrigo Valdez.

 

Marvin Hagler vs John Mugabi

 

Evander Holyfield vs Mike Tyson

 

Marquez ko 6 Pacquiao might be the greatest one.

 

Manny Paquaio vs Keith Thurman.
