Ken Buchanan looks impressive in the carear highlights videos.
He had a Great Jab. Underrated elusive defensive movement as well.
He was deceptively Quick and Strong. Tricky,clever,smart,instinctual minded. Very Tough and Brave hearted Fighting Warrior Spirit. I could see him holding his own against any LW in any era. It Stinks what happened at the end of the 13th round vs Duran. The bell had already rung, before Ken was smashed in the testicles. I've always been a Huge fan of Duran, but that was for sure his Ugliest moment. They should have at least just simply gone to the cards,instead of ruling it as a Tko13. It then would have been a TD13 win for Duran, as kooky as that sounds.
Also, Buchanan Should've Definately been given an immediate rematch. From what I've researched, He Did in fact want another crack at Duran, but, Duran's management chose to avoid a rematch against the Very Skilled and Tough Scotsman.
I think that a second bout would've been Great, just as they're first bout was. Likely, Duran had Ken's number, based on the styles making fights aspect. Still would've been relatively close though. In they're first bout, Buchanan had his moments but Duran's pressure style and iron will was just a bit too overwhelming for the Game Scotsman. Like I stated though, I seriously think that Buchanan would've been a Tough opponent for literally any Great LW from Any Era ! His style was Quite awkward so it was Very difficult to catch Buchanan with a clean hard shot. And his Quick Powerful efficient jab would've given even Very fast tricky guys like Sweet Pea, some serious fits. Would Arguello land the home run punch against Buchanan..?
Maybe, but Ken had a Very Good Resilience to Ko Power Punches. I don't think that even the explosive thin man would've been able to put away the Very Game Scotsman Fighting Warrior.
Now, with Ali, my main criticism is that he,or his management, didn't give Foreman a rematch. For whatever reason. As I really think that he,or they,definitely Should've !
I can't Really just blame Ali though, cause, like Duran not rematching Buchanan, due to the decision of Duran's management, so too could've been the case with Ali not having a second bout versus Foreman.
Both Ali and Duran had Great credentials in the ring. Skills, Courage, Fortitude, Resilience, Iron Will, amongst other fighting Warrior attributes. So many hypothetical matches that one can drum up and imagine, pertaining to these Legends of the Ring. Ali vs Foreman 2, Prime Ali vs Prime Joe Louis, 1967 version of Ali vs 1982 version of Larry Holmes, Ali vs Lennox Lewis, Ali vs Mike Tyson,Ali vs Bowe, Ali vs Holyfield, Ali vs Wlad Klischko, Ali vs Tyson Fury,etc,etc.
Likewise for Duran...
Duran vs Julio Cesar Chavez, Duran vs DelaHoya, Duran vs Pacqiou, Duran vs Sweet Pea, Duran vs Arguello, Duran vs Buchanan 2, Duran vs Henry Armstrong, Duran vs Benny Leonard,Duran vs Money Mayweather,etc,etc.
I'm not saying whether or not Ali, or Duran would win or lose to this guy or that guy. I see Boxing as being too unpredictable. It's almost actually like baseball in that regard. They're both highly respectable Legends and arguing who is better between them two is similar to arguing who is better between the comparisons of 1968 Bob Gibson vs 1985 Doc Gooden, or 2021 Jacob DeGrom and 1978 Ron Guidry. Or who is a better legendary batsman, Ty Cobb or Ted Williams...?

Tony Gwynne or Rod Carew...?
