If LHW's are actually cruiser's on fight night (176-199 lbs) and cruisers are actually heavies (200-225 pounds) on fight night, wouldn't that mean that many ATG heavies like Ali, Tyson, Holyfield, Louis, Liston, a younger Foreman, Fraizer, Holmes would all be cruiser weights with day before weigh ins? Or old time (or not so old time) ATG LHW's like Spinks, Foster, Charles, Moore would be middle weights with day before weigh ins? And if not, what's the difference between a cruiser who is 218 pounds on fight night and Tyson when he was 218 lbs and HW champion? Or Bob Foster in the ring at 170-175 and GGG who may be about 170ish on fight night?
