The 1963 version of Sonny Liston was allegedly 33½ years of age and had competed in 36 bouts.
He had lost one of them and had gone the distance eleven times. He wasn't as heavy-handed as many believe him to be.
The average weight of Sonny’s opponents for the first 36 bouts of his career was 196lbs, which is much smaller than today’s cruiserweights (who all have to dehydrate in order to make weight).
Liston’s average weight during the same period was only 207lbs and he wasn’t particularly well-muscled or defined either.
Sonny’s jab was excellent, but his hand-speed, head movement, work-rate and foot work weren’t. He was a tough slugger that got the job done.
Apart from Oscar Rivas, I can’t name a single modern-day world-rated heavyweight fighter that is shorter than the 1963 version of Sonny Liston.
Even Oleksandr Usyk and Deontay Wilder outweigh Sonny Liston, with both guys being much taller than the American all-timer.
Sonny received a lot of hype during his own era, but he wasn’t particularly accomplished, other than his victories over the undersized Floyd Patterson.
He deserves his place in the IBHoF, due to his historical contribution to the sport of boxing, since his story/legend is fascinating, but unfortunately nostalgia compels many people to believe he was capable of things we never actually saw him do inside the ring.
Liston definitely loses to the majority of today’s (mathematical average) 6’4” 245lbs world-rated behemoths.
