How old are you lad !
Ali in his prime would have made him look a total hick, if you think Tyson was fast it really does show how young you are, Ali was different class & deffo the Best since the second world war. Like Tyson , Ali carried on too long & became a shadow of what he was in his prime.
Now Tyson against Marciano would have been a great contest & believe me Rocky would not have fallen over as easy as some of those guys whatever Tyson threw. He was the only Heavyweigh Champion to retire unbeaten & would have out brawled even Tyson. Over the last 15 years Tyson is the best I agree.
