Dundee specifically said if Ali wanted to fight he would be there. I'm sure Veronica his then wife didn't want him to fight anymore but he was hard headed and loved the limelight.
Ali was known to have failed a test, he couldn't stand on one foot and touch his nose, but what were they going to do, cancel a multi million dollar fight. Watch some of Ali's interviews while he's training for that fight, he's slurring his words like a guy with a .25 BAC. Pacheco knew what kind of shape he was in and warned everyone in Ali's camp but,,everyone Including Dundee WERE GETTING PAID.
Who was going to stop him? King promoted those fights. I wonder if Arum would have if King didn't. He seems to have a semblance of a conscience. I don't belive King liked fighters because he was jealous of them.
