I just wish they were more like the Spinks because i pretty sure they might try to kill one another and i get to see one man stand on top know he is the guy. The list to me is not a head to head thing really and i judge eras from the 60's back differently from now. I rank the brothers in top ten from 80's to 10's were i rank them i do no know because i would have to really look at what every one has done. The old timers did not have any of the advantages we have today like peds and nutrition we have today. Only way i could judge them is if we could get them in a time machine and let them have all the advantages then fight that would be the fairest way i guess you could do it. Thats a hard ask though so i tend to just go by dividing up the old and new eras when it comes to heavyweights not so bad with other weight classes.
