yeah, it'd be great to see him go 51-0, retire and then have some documentary made on him, let the fame build up, comeback so he can finally make some decent money go 52-0 and retire again as a legend (and be an irritation to Floyd at the same time as he would have broke his record without a joke fight against a debutant)
If he retires at 50-0-0-0 as a reigning world champion, that will be a first in boxing history, he will definitely be a legend, especially much later. That will outdo Floyd Mayweather 50-0 (he was reigning 49-0) Past attempts failed near 50-0 in title fights, this fight might force Floyd to come back and go for 51-0 in a title fight vs the stylistically suitable world champion (Traux 168, Canelo 160, Sadam Ali 154)
