The second half of the 70's was one of the very worst eras for the heavyweight division... ever. It was an absolute disgrace only marginally and sporadically improved by Holmes.
If Foreman could've manhandled Terry the Tornado Daniels like that, he'd have butchered Ali in one round in a rematch...
It really seemed like Foremans mind had gone the way he just stopped the fight to start shouting at Ali then the corners fighting. He then attacked his own cornerman! I don't agree that the late 70's was that bad. It still had some good names but was far inferior to the first half of the decade.
