Now i think max power makes some good points about modern heavyweights, the sheer size of guys these days has changed things quite a lot, and it is very possible that they do hit harder then ever , just going by size, but obviously there are a lot of other things to consider too.... I like the heavyweight division and dont think it is anywhere near as bad as it is made out to be but size isnt everything .. Wehn haye came up to heavyweight he had some good results and could ko heavy guys like chisora fairly easily and he only weight 210-220 pounds he willingly came in lower than his usual heavyweight weight to face wlad and didnt come close to being ko'd, so to say ali who was a similar size to haye would be b level because of his size is juts wrong I think.
