Longest PEAK Career runs...

Modern era is Floyd Mayweather. He really wasn’t all there for Maidana, Pac, and Berto though.

 

John L Sullivan was the best heavyweight in the world from 1880 till about 1890 or so, and most of this time second place wasn't even close.

 

Yeah I am calling bullshido here.

 

Take it up with Adam Pollack. It's his argument. His contention is that the distance between Sullivan and his nearest contenders was greater than at any other time in the division's history.

 

You could make the statement about every pre-1960 champ, possibly some after.

 

The closest competitor here is IMHO - Marciano. 49-0-0 (43 KO)

 

I do not know the answer but, unless I am mistaken hardly any of the responses are responding to the actual question. If I am wrong I am quite positive you will all beat to within an inch of my life. I have always thought of peak as the very best of a boxer's prime years.

Ray Robinson and his 129-1-2 record has been mentioned often but those numbers start at the beginning of his career and he was hardly in his prime, let alone his peak, in the early 1940s. The same goes for many of the fighters mentioned.

Prime and peak are both areas of opinion and, as previously stated, I don't know the answer but I will throw out this modern-ish example. From May 1994 to September 2002 Roy Jones had 23 bouts which included 20 or 21 title fights. Those fights included 152 complete rounds which would equal 456 rounds of judges scorecards. Jones was the winner of 424 of those rounds and lost just 32. This does not count the 12 rounds where he KOed his opponent or the round he was DQed after putting Montell Griffin on the canvas. Basically, Jones won better than 13 of every 14 rounds over an eight year period. That is quite a peak.

 

That would be my pick.
