He seems to have lost alot of clout the last couple yrs or is it just me persceving that? Great fighter IMO
He was a beast, and he cleaned out a solid group of heavies (Machen, Folley, Williams 2x, Valdez) and then crushed Patterson twice. However no one knows how old he was for Ali and the way he lost both fights leaves lot to be desired, quit on his stool in first match as he was losing and then whatever you believe happened in the rematch. But he was knocked down and didn’t quite put up the strongest protest in the stoppage.
In my opinion prime young Liston would be the favorite against anyone although vs. Ali would be about even money. I think his reputation really got tarnished by the Ali fights. Only God knows how old he really was...
