How long would Ken Buchanan have reigned if....

old glass balls kenny..loool jk great fighter.

Joking aside besides Roberto he was definatley the most technically skilled fighter. He was never gunna be a superstar like most of the greats but he was an extremely tough and durable fighter, not only that but ring savvy and patient as well. All technical aspects of being a champion covered i dont see why he wouldnt have remained champion half a decade longer. Duran was just a supernova, bigger than the division
