Good point, Terry, I've seen Ali/Shavers a couple of times. I scored it 8 rounds for Shavers, 6 for Ali and 1 even.
This was another fight where Ali was p1$$ing blood afterwards. I read that after this fight, Ali's doctor, Ferdie Pacheco, sent copies of tests showing that Ali's kidneys were nearly falling apart to Herbert Muhammad, Angelo Dundee and Ali himself. None replied, so he quit Ali's corner.
'look back on Ali's career and look at how many fights were stopped by the referee' - yes, the Ron Lyle fight springs to mind.
