A Young Ali Against His 1974 Onwards, Opponent's?

Beats them all and that much more easily - and of course he doesn’t lose as he did to Spinks, Holmes and Berbick. Ali beats Holmes clearly and both Spinks/Berbick easily.

 

Regarding a younger Ali vs Norton.

Eddie Futch was asked after the first fight if Norton could beat the Ali, of say, 3 years earlier. Futch emphatically said definitely not and said he turned his speed and technique on and off and couldn't go that route constantly anymore.

That's brutally emphatic regarding Norton's chances vs an earlier Ali, and by the man that would most certainly know.
