I think fighters should only be 'rated' at and remembered at The ONE Weight which was their true and best weight. that would excluded Charles, Moore, RJJ and a few others obviously. I don't see Europe being represented much here, Eubank for example could be easily replaced by much better fighters in Jock McAvoy, Bert Gilroy, Randolph Turpin and Robert Villimain, again just to name a few!
jones' best weight was 168 but i see your point. btw, jones would win this tourney if it were to really happen but he doesn't stand a chance on the classic boards. it'll be nice to see him in fantasy matchups at his natural weight instead of being put against every heavyweight that has fought in the past 100 yrs.
