I don't really get it, it was obviously choreographed so Ali must have agreed to 'lose' the fight?

I might have to read up on it some more. I know Marciano had been retired a while but had enough competitiveness to lose a fair amount of weight to do this but how did they come to this conclusion?

Marciano was never that slow during his best days and could be very explosive, he certainly had the power to stop Ali but he was horrendously slow in that video, it would not have been a fair contest.

Not really sure what I'm trying to say but interesting video.
