Yes. AB stopped them all. I must go with the man that nobody has been standing to see the final bell. That type of record screams bad ass.
Or Kovalev. He wasn't the toughest, but dude was absolutely ruthless in his prime. Literally killed a dude and then continued on as if he wanted to kill every other opponent too. Absolute savage.
Probably Beterbiev....................or Wilder. Those two men are probably the two guys that had the most fearful aura around them.
I dunno, I remember reading in an interview where Kovalev said the death of Roman Simakov weighed really heavily on him and I think it was a significant contributor to his alcoholism. He acted like a bit of d*ck outside the ring, and in it he sure was violent, but he wasn't heartless I don't think and I don't think it's right to make light of the deaths of the courageous people who put their lives on the line for this sport.
I am fully aware of how the death affected him. I think he financially supported the family for a while too. But the way he boxed afterwards just shows you how savage of a man he was. He was born for boxing.
Beat up "literally who" De Mori and scraped a win over Zhang.. His career at the top level hasn't started yet?
Dereck Chisora is the toughest & baddest fighter in the last decade for sure. Hate him or love him he has fought anyone and everyone in the heavyweight division.
