My man Buchanan was a natural LW and fought his whole career at that category. He lost a controversial fight against Duran. Afterwards Duran dogged him, refusing to face Ken again. Duran has always said Buchanan was the toughest opponent he ever faced. No Marvin, no Sugar, no Tommy, just old plain Ken. Buchanan is gonna blow that bloody Castillo wanker to the moon and back.
Castillo would enter the ring at 150+ and roll over Buchanan. Castillo wouldn't even make weight in same day era.
