Barbados Joe Walcott punching power

can you tell me in which article johnson or sam said that? would prefer the link

 

Here is the quote:

“Jeffries number one? No, sir. Give me Joe Choynski anytime,” Johnson said. “I faced both and I should know. Jeffries had a powerful wallop, but Choynski had a paralyzing punch. His left hand was a corker. He was the hardest puncher in the last fifty years, with Joe Walcott a close second. I think his left hook was even more effective than [Jack] Dempsey’s. Choynski could paralyze you, even if he didn’t catch you flush.”
