Sonny Liston a very good fighter. He had a superb jab, a solid chin and awesome power. Too much stock is read into the Ali fights I feel. I'm unsure about his whereabouts in an all-time list but I do think people are too nostalgic about the past champions. His cheating in the Clay fight coupled with the phantom punch in the rematch definitely leave a bitter taste in the mouth but it has to be remembered, Liston wasn't a quitter with no heart. In one fight he fought six rounds with a broken jaw and still won, that takes a lot of heart. In 1974 Ali said of Liston, "He hit harder than George, he had a longer reach than George, he was a better boxer than George...". High praise.
His jab was something else though, it really warrants credit. 84" long, which is the same as the taller Lewis and Bowe, plus, for a long armed fighter he was extremely good on the inside. He had that clubbing right hand, the savage uppercut and one of the very best left hooks in heavyweight history. His true prime, between 58 and 60, Liston had, at worst, the 2nd best jab of all time. Seriously.
