You said it! I’m often too lazy to be so thorough in presentation, and this is one of those instances. I will say Liston’s pre title resume is formidable and the stalling of a shot has to be factored. However, there is a measure of counter balance re the due and extra credit afforded for successful title defences. It’s often said it’s easier to win the title than it is to hang on to it. This is true at several levels, not the least being that challengers will often bring their A game for the big prize, some even rising above their substantive rating. But another spanner is that Liston was old and beyond prime and shortly thereafter faced no less than Muhammad Ali who went on to reign acutely supreme. I do think that Evander was more mentally committed in uber tough fights but then that’s mainly comparing him to the Liston who lost to Ali and a few fights of Sonny’s going forward - that’s not necessarily the last word on a prime Liston however.
