Liston V Rocky's Title Challengers???

The Marty Marshall loss ? Liston was very much a novice at this point.

 

I actually can't think of anything Marciano had which Liston didn't have more of except maybe stamina. Both probably had about the same amount of power and chin. Liston looked slightly faster, somewhat better technique. 2 1/2 inches taller with 16 inches more reach, and twenty pounds of muscle. Unless the mob told him to throw a fight, I see him knocking out all of Rocky's opponents the same way Marciano did.
