I'm not sure Buchanan won any rounds clearly against Duran, though the fight was more competitive than is often made out imo.Duran had two huge rounds and the rest were split about evenly between competitive but clear for Duran and close enough to go either way.The judges cards at the time of the stoppage were about right imo.
pretty much how i seen it pretty close rounds with duran getting a small edge real good book called tarten ledged or something well he went over to New Yrk to look for Roberto and ended up staying in Queens with a black lady he then went to a pub where the guys recognised his accent and asked if he knew Buchanan and he told them who he was and tehy got talking about boxing and they wnt for the pub for around a week and Ken asked them if they knew where duran was but they told him its like a needle in a haystak so he went home (just realised i told tahtreally crappily)
