There is no need for discussion about the best CW ever - every normal persons would agree. Of course, his name is Evander Holyfield. The number 2 could be questionable, but I will vote for David Haye. I have to mention Usyk, he has a great potential, but , personally, I would like to see him at HW, as soon as possible.
Yes, he defeated Mormeck....And what is your point of view ? David Haye was better CW than Adamek (a level above), and he is/was much , much better HW - two levels above..... I wouldn't like to be missunderstood, I consider DH a great boxer, potential HW champion, but, very often I do not support his behaviour. Simply, he should be more polite.
i dont rate haye as a top fighter, full stop. he is simply the most overated fighter of the 21st century.
OK, Cruiser Weight Division had been established 1979. You mentioned Marciano, but omitted Louis, and young Ali... I mean only modern day CWs...
any crusierweight today can fight at 195lb for the heavy title and weigh in at the cruiserwight limit so marciano at 185lb is a legit cruiserweight . truth is all cruiserweights want to fight at heavy because of money / and cruiserweight has always been seen as a stepping stone to heavy. there has hardly been a mainstay cruisrweight since the division started / johnny nelson maybe but he was terrible in his early attempts / haye is most probably the best cruiser/heavy since holyfield since the introduction of the division/ toney as was his want only had 1 fight of note then saw a kentucky he liked and stayed there for a month and became a heavyweight.
