Great Post. Harada also retired at 27,and he was a hard trainer in the Gym. Was he not a great little man? Chang's opponents are great resume wise, and even better H2H in my view.
Yes, most astute boxing observes generally DO NOT pick Chang's quality of opposition as strikes against him. He took on all comers in his prime years. I suspect Mendoza does not know the era well, did a BoxRec search on Chang's page, and automatically struck off anyone he didn't know as a "stiff" - when Chang was already fighting a future flyweight world champ essentially in his first fight (the "Rookie King Tournament" generally took place within a 2 week frame, and you had to fight 5 or 6 times to win), and that he was wrecking a respected former champion 1 year after turning pro! Chang was brought up super-fast (another Tyson parallel), because his management knew that 1) he needed to maintain his focus or else he'd go off rails, and 2) he was not going to last in the sport due to his off-ring habits.
What was your scorecard? I am sure that you of all people don’t comment on fights you have not watched?
I might quibble with your terminology here. I agree with you if you want to take the slower and less active Chang that actually fought as flyweight against Kittikasem or Chitalada. But if you just take prime Chang and have him fight at flyweight, then I cannot. It's not a big weight difference, and many have made the transition rather seamlessly. In fact, quite a few Chang beat at junior flyweight later moved up and became flyweight champions (Hi-sup Shin, Zapata, Chitalada, et al.). Anyways, this may be my all-time favorite thread at this forum, and reading it second time is no less humorous
A while ago someone asked Chang how he thought if he ever thought about moving up in his prime, and how he would have done. He replied that it never really came up, because he was focused on breaking Gushiken's all-time defense record. But he thought he would've done just as well at flyweight - and possibly better, because making weight would've been far easier, and that was one of his most persistent issues. I wish he had done so after the third Torres fight, because he had nothing to prove at junior flyweight.
To be honest, I actually agree with you on that. It was just a bit too hypothetical for me to give as a solid choice on this thread.
