Ring mileage (fights/sparring), previous ko's, weight issues, age/legs, overtraining, mental factors, alcohol abuse
seems like an internal clock for each individual fighter. some never reach their limit and end up fine. you could have a guy who may be blessed with a great chin for the big shots, also be naturally predisposed to take more shots over the years than others, AND have great defense...but once any one guy's "limit" is reached, the punch resistance seems to become an issue.
even though there are warning signs trainers and handlers can see in a fighter who is slipping, others don't find out until they are in the middle of a fight and it all unravels. plenty of examples of older fighters who seem worn down but still go out there and compete and hold their own and others who have to get out in their mid 20s because they're already shot
