If a young Sonny Liston had been around in the 1970s instead of the late 50s and early 60s?

Sonny Liston was without question an excellent boxer / puncher, But liston lacked mobility which Eddie Machen and Muhummad Ali would later prove in thier fights with Liston. It is fair to say that sonny Liston could have possibly beaten George Chuvalo, Jerry Quarry, Oscar Bonavena, Mac Foster, Ron Lyle, Earnie Shavers, Joe Fraizer, Henry Cooper, Karl Mildenberger, Ingemar Johansson, Jimmy Ellis, Ermie Terrell, and Joe Bugner.....nuff said !
