The 1950s is still during the apparent "madatory" rematch clause era, so do you think Louis has a chance of regaining the title?
He's losing more often, but if in his prime would also be the champion. I just do not think it would last for many years. The 1930's and early 40's were very down periods of heavyweight boxing. Joe Louis best wins, in my opinion, were Schmeling and Walcott. The problem is he lost to Schmeling via TKO and should have lost the 1st Walcott fight on points. I think we all agree that Marciano and Liston were better than Schmeling and Walcott. In addition, you can find statements on the web where Louis said he would have never beaten Rocky Marciano because he didn't do well vs crouching fighters and did not like to be crowded. Bottom line, Louis defense and chin would be tested 2x more from 1950-1960.
Marciano also said he would never have beaten a prime Louis. I think they were just trying to be nice to each other. I do think Marciano could have beaten Louis- prime vs prime. When asked how he would have fought Liston- Louis replied "with a gun".
No ,you found uncorroborated statements that Louis said that but, when asked to provide a primary source did not come up with one. Louis called Marciano a street fighter,so did Walcott ,and this was after they had fought him. Since you haven't seen the complete Louis v Walcott 1 fight, only edited high lights ,you have no historical basis to say Walcott should have received the verdict. I'm not totally convinced that Marciano beats the version of Walcott that faced Louis. It's all just more Louis bashing from you ,something you have a history of.
