Yeah, I'll admit that the old-timers don't excite me much. Low hands, grappling, sloppiness...I'm not that impressed either.
To be fair Janitor, you only asked who has been on a par with Louis in regards to punching. Mike Tyson is definitely up there. Anomalies don't prove or disprove boxing 'evolution' anyway.
I look at him as a complete man. You have to consider Jim Crow south. A black man that destroying white fighters and dating their women openly, first black HWY champion that is using a style for his era that is effective. Of course like any sport it evolves, but for his time and considering the man and the athlete, and that man that Ali molded himself after is saying a lot. Its easy to look at him on the outside and say, that's not so great, but I'm sure the men he fought also said the same thing.
