Just to look at Paddy Holohan fight, it's pretty obvious that he was a fighter making every possible sacrifice to get himself into the cage. Rail thin, un-athletic looking, under-powered; Holohan won bouts by flinging himself body and soul at opponents, daring them to out-fight him moment to moment or risk getting overwhelmed by his enthusiastic aggression. A man who wasn't physically built for fighting, making a career out of it with the power of will.
Sometimes appearances hit too close to home. It seems Paddy Holohan's body really wasn't made for a career of professional combat, and now he's been forced to retire.
