I Have To Believe Jeffries Durabilty

I wasn't questioning Fitz's durability , just your statement that Jeffries was the first to ko/ floor him. obviously you wrote that in a hurry.
Wet plaster of paris on your hand would set, and be as damaging to the bones of the wearer as to the face of the receiver. Jeffries examined Fitz's wraps prior to the start.

News paper speculation years after is not proof.
Fitz cut Jeffries badly around the eye in their first fight, it was not a unique occurence for him to have facial damage whatever he said.
I've used electrical tape on my hands ,[Dempsey may have worn it at Toledo,] after an initial ordinary hand wrap , then ordinary wrap on top ,it makes your hand into a solid mass without damaging your own bones but after a few rounds your hands get numb as there is little or no give in it.. But by then your opponent is usually ready for bed anyway. These were not regulated boxing matches BTW.
How's the Johnson story coming along?

 

Jeffries beat one 200lbs man of any class who was near his prime, so what is wrong with my statement?
Munroe was rubbish . Jackson was a wreck.

Jeffries best wins were over . Weight advantage
Fitzsimmons.37 & 39years old, 167lbs & 172LBs. 39lbs&47lbs
Corbett. 33 & 36 years old,188lbs & 183lbs 27lbs&30lbs
Sharkey . 180lbs & 183lbs. 25lbs &32lbs

The heaviest of this trio was Corbett in their first fight 188lbs that is 12 lbs south of 200lbs. I never mentioned 220lbs that is your invention.
Fitz was inside the Lhvy limit for both fights.

Jeffries had huge weight advantages in his 6 major fights, and significant age advantages in 4 of them.

I've unequivococably decided Jeffries had a top drawer chin.
What is your point?
