I mean there was a period of like 3 years in the late 60s where he wouldn't fight anyone. What was that all about?
Haha Wait! But those are inexcusable and you are instantly a ducking, unworthy ***** whose past achievements should be null.
Of course I was joking. We actually never saw Ali's peak, which would have been sometime after his fight with Zora Foley and before his comeback against Quarry. We only saw his rise, and his decline. We can only extrapolate what his best would have been. One of his greatest legacies is that he fought everyone from his time, and did so all over the world.
