This has been debated endlessly. You could be right (except you rounded down Liston's height, the opposite of what folks do usually), but having a very wide chest & huge hands means it is possible. The longest "ape factors are 11" (wingspan more than height), & one guy is even longer... Anyway you can argue who would win either way. But I o not think Fury's greater size would make it near impossible for the quicker more agile Ali to land & move in & out. Also Ali adapted very well, even on the fly. He would not at all be married to not going to the body if that made it much easier to score on such a large target. he even went ownstairs in his brief dazzling fight with Williams.
