Not quit the 'Thrilla in Manila" or "Rope a Dope" in Zaire, and other Ali-Frazier-Foreman classics, but right up there next to those 3 greats.
At that time, it looked like Tyson was going to own the Heavyweight belt for a decade, and seemed invincible, until this classic upset.
Yet, I still think Cassius Clay's KO of Sonny Liston was the one fight that took my breath away, tho' I prefer the Clay/Ali vs Foreman slugfests.
Yep, Norton broke Ali's jaw, but Spinks, a big scrawny underdog, took his brand of Alley Fighting to Ali, who would of ever thought so???? Another big payoff to the underdog....!
