There are many reasons why Fury’s career blew up in his face. First, he failed drug tests, something that many people conveniently forget. But he also developed serious drug and alcohol problems. He consumed cocaine like a child eats candy. He also admitted that he drank 12 pints of beer per day.
Fury blew up to 400 pounds and his partying lifestyle took its toll on his body. It’s remarkable that he turned his career around and returned to boxing after this traumatic experience. He had some great fights with Deontay Wilder after this but has recently ducked clashes with Anthony Joshua and Oleksander Usyk (via Planet Sport).
