If you looking for unbeaten streaks not necessarily from the start of the career, Packey McFarland had gone over 100 bouts without a single official or unofficial (no-decision) loss.
He was DQ'd for landing a shot just after the bell which sparked his opponent. Changed to a KO win the next day, think it was his 11th fight.
I did a thread on this a few years ago, and never really got a good answer...or rather good information, story links etc... I was watching my copy of chavez vs lockridge and Chavez is announced and depicted on screen as having one loss.... I heard alot of coruption from the mexican boxing commision, but again nothing substantial was brought to that thread.
Yep correct, thing is records shouldnt change perspective of them, Rocky drew a fight aswell which the ref gave to him as they were trying a new method of scoring and stopping draws.
