If being stopped twice in about seventy fights, with about a third of them being championship fights and one of them being at the tail-end of your career by a vicious HOF puncher makes your chin doubtful, then yes. He was under glass suspicion.
Here, yeah. I'm thinking that if maybe Kid Gavilan had just stood along the ropes and let Ike Williams and Carmen Basilio batter him to a stoppage loss in the early rounds rather than take the only 2 KD's of his 143 fight career in which he never accrued a loss by KO/TKO/RTD and get up to win those fights (and he did, from most all accounts) then maybe his chin could be on the level of Chuvalo. He would have never been knocked down. :shock:
He was KD'd by Galento and Jeffries. The Jeffries KD was flash in the 1st. The KO loss to Schmeling is against a HOF'er who wore him down late, not so much a weak chin at all. Walcott dropped him good twice I believe in their first fight. By that time Louis was so far past prime though. He stood up to Max Baer, Primo, Ezzard Charles even when post retired, big boys in Buddy Baer X2, Abe Simon X2, I don't think Godoy or Pastor dropped him in either of their two fights each. Keep in mind the era with gloves n all... Most offensive fighters will sacrifice a particular area of their game and also leave themselves open to such shots. As a 1930's-40's HW with an iron what 66-3 record, he has a rock solid chin.
how would anyone in the history of the world fare against a shot from a prime foreman. louis' chin was cracked before, but it also stood up to hellacious shots as well. look at his fight against marciano. he was eventually stopped, but he took some serious bombs in the buildup to the stoppage.
Not the hardest man to knock down admittedly, but extremely hard to keep down. His opponent usually paid a dreadful price for the honour of knocking Louis down.
