Main SINGLE reason there was no Ali-Foreman rematch?

Foreman did not want it.

Truth be known, I bet Ali didn't want it either. Foreman seemed to fall apart after the Ali fight, i've even heard him say how mentally devastated he was by the loss in interviews. Just goes to show how much of boxing is mental, George had the physical size, strength and power to demolish Ali, but he lacked the mentality to carry it out. I always thought Big George beat himself in Zaire, perhaps because he didn't believe he was worthy of beating a great champion like Ali.
