Umm in his prime he is up there he just come at a time when Ali was at his peak no shame in that what hurt him was controversy over the 2nd fight with *phantom punch* but he would beat alot of hws and if he was in with todays hws he would clean out divison and been undefeated only one that would give him trouble is of course Wlad but i think Liston would crack that glass jaw of Wlad.
