Nobody that got knocked out cold 2 TIMES by ONE punch by two different fighters has an iron chin.. I don't care what you say.. Iron Mike had an Iron chin!
i dont think being up by the count of 6 can be classed as out cold im afraid, good try. If you think the Rahman loss was the reslt of only one punch as opposed to a final punch ontop of the culminative damage then your assertion about Tysons iron chin cant stand either, in that case by your logic we can say hat Tyson was knocke dout by Lewis by one punch! Think about it.
What a bull****, there is maybe 2 or 3 shots on Levis chin in that long video. What the video represent is a great Lewis offensive skills and ..... IRON chin of Tua who took like a man all Lewis could throw!
