Tony Tucker dances and jabs but eventually gets hit flush. I would think it would similar to the loss to Tyson in so far as he dances and moves but Liston had a huge reach advantage over Tyson, so probably would connect more and get Tucker out by round seven or eight.
I do not think that Tony Tucker has any TNT in his punch to keep Sonny Liston from inflicting pain on him. Liston stood at 6"1, weighed 218 lbs, needed special wraps and gloves to cover his massive well documented 14 inch fists, according to corner man, Milt Bailey. The Bear engages Tony into a boxing duel early, but then dodges Tucker's counters, to land his thunderous right hand to end this encounter in round 7.
