In a sense it was the rope a dope method Ali used to defeat George but in reverse. I would call it "The squared up beat me up" Foreman method. He took a lot of punishment similar to Ali but stood in the center of the ring instead of using the ropes.
I just last night watched a documentary about that fight on YouTube and Moorer himself said he was out on his feet from the right George hit him with a few seconds before the finisher.
