"...crazier than Juan Manuel Marquez, who used to find strength by drinking his own urine and who now has settled into an Ahab-like fixation on defeating Manny Pacquiao, something he hasn’t managed to do in three previous fights."

An Ahab-like fixation does not make a person crazy. It's a deep commitment.

Drinking his urine to find strength, however... Yeah, that's nuts.
