I never noticed that. Paul Fuji was the Jr Welter Champion Yoshiaki Numata was the Jr Lightweight Champion Mitsunori Seki was the Featherweight Champion Fighting Harada was the Bantam Champion Chartchai Chionoi was the Flyweight Champion The LHW Champion was an African, Dick Tiger... and the LW was Carlos Ortiz. And 3 americans, Ali, Griffith and Curtis Cokes.
A bit sad isn’t it. As much as American Boxing has given us, & it is a lot, I do wish it had more of a global flavour. I can’t believe I just halfway made an argument for diversity! First & last time.
