Re: debunking the myth of louis being completely past it ...
Charles didn't have the leg speed in the Marciano fight or in those two fights posted above (Wallace and Satterfield).
Yes, he was still a very good fighter but he's a more static fighter than he'd been 4-5 years earlier.
It's not at all controversial or worthy of debate. Charles was past his best, clearly. He just didn't move the same as he had at age 27 or 28. So he had to absorb more punishment and stand and slug more.
