Two degrees of seperation - can you beat this?

Chuvalo actually started as a pro before Peralta.

 

What about Duran? He was around 5 separate decades. I can't think of the greatest span of his opponents off the top of my hand.

 

Jem Mace sparred with Philadelphia Jack O'Brien, who sparred with Joe Louis!

 

You can get close with Angel Robinson Garcia:

He faced Felix Alfredo Triana who was boxing by at least 1945 and also faced Saul Mamby who boxed until 2008. Just under 65 years.

 

You can get 64 with Archie Moore.

Johnny Romero debuted in 1927.
Muhmmad Ali ended his career in 1981

 

Tried a few but couldn't top 50 years.

Britton had a long career so there might be a few with him.

Duran and jack johnson also.

 

I can get 56 with Duran. Dont think anyone will beat archie moore

 

Mamby might be the man to go to.

 

The only 'flaw' in this is that fighters nowadays continue fighting into their fifties which will obviously increase the span. Rarely did a fighter go past 40 in the 'old' days. Even so, had Holmes hung up the gloves in the late 80's we're still talking 50 some odd years after Archie's debut.

 

I was just gonna say that

 

that's 54

 

Bobby Dobbs fought for over 5 decades and a reported 1000 odd fights (including Booth fights in the UK), I'll bet there's a chance Dobbs beats it!

 

i can find 56+ with foreman. just depends how longer shannon briggs or holyfield fights

 

I got to sixty using Mamby.
