who was the most ferocious?

Jeff Fenech ,no slouch in the ferocious department.

I'm not sure Johnson took delight in hurting his opponents. He often carried opponents, which is not the usual activity of someone who really enjoys beating them up,...... Johnson liked to humiliate certain opponents, which is different from hurting them - and he only really did this to Burns and Jeffries. He certainly didn't try any funny stuff with Joe Jeanette for example.

As he could seemingly pick and choose which people to humiliate, and because he carried his opponents, I would not classify his as 'ferocious'. He could be, he was a great grreat fighter, but he was too canny to be hell bent on destriction while in the ring.

It doesnt seem that way watching his fights now,but Id put Ali in to the mix,the way he'd just decide he was bored with you,and end your night,because there is a ferociousness that allows you to toy with someone like that. Because you know he could have ended it whenever he pleased.
Ann Wolfe definitely has to be in the mix as well,come to think of it so does Valerie Mahfood,on the womans side of it,I dont think either of them have ever understood the word reverse.
Manfreddy has to be in there as well,you allways knew were Angel was going to be,right in front of you throwing punches,Mancini was like that too.
