There is no doubt Floyd is an incredibly talented fighter. But he hasnt been in the position that many great fighters in the past have like regaining a title, avenging a loss, getting off the canvas to win, or making a mark on the sport that goes beyond ring accomplishments. Im not saying that has to lose a fight to be considered an all time great, though eventually he probably will as do most fighters cause after all he is only human. But, his career is not yet complete imo. I often wonder where Tyson would stand in the history books if he retired 37-0 before tasting defeat. There would probably be people saying that he was a top 3 heavyweight of all time today. Can Floyd retire after one or two more fights and be considered an atg, yes. Can he retire now and be considered an atg, sure, but I think its a matter of opinion and there are unanswered questions for some.
