How Does Cutting Weight Affect Punch Resistance?

[elfag]

Look at Ali and Foreman's chins in their 2nd careers when they were heavier vs their first.

Chris Byrd was a good shout too by that guy above. How can you have a career at heavy with a good chin but then get KTFO by bums at 175?, loosing all that weight.

Cotto too, he was getting rocked by torres at 140 but took harder shots at 147. His stoppages were accumulation where he took a beating and much worse that when he got wobbled by torres.
