This list of mine was just a quick run down of some that came to my mind. I wanted some input so we all could get down to a solid top 10 list! So far there have been some great choices, so keep your suggestions coming:!:
Calzaghe. Underrated toughness because most people think he was all about speed. Never seen a more relentless fighter than him.
Joe Frazier Chuvalo Ray Mancini Glen Johnson Chavez Ray Mercer Mathew Saad Muhammed Bobby Chacon Iran Barkley Bert Cooper Manuel Medina I have Ray so high because of his fight rematch with Bramble, he took a pasting in that fight and i would of put money on him not going 12 let alone 15, he damn near almost won it in the end to. Ray was not a smart fighter but he had tons of heart.
I'm going with current fighters so i'll say. Hopkins, Andrade, Adamek, Penalosa (even tho he just retired), Pavlik (you have to be a great like Hop to take him out) and Froch.
Who cares. Let George Foreman hit you like that and see if you want to fight on. You question Cooper's toughness you are crazy. Cooper vs Holy,Mercer,Moorer,Tillman :-(
Thats a pretty much impossible job RR, you'd need a top 20 or 30 cause there's that many guys you just COULDN'T leave out, even then placing them would be impossible
