Right off the bat, I think he's lost vs Yuri and Too Sharp, they're too big for him. Laciar may be as well, I definitely think he's too strong for Chang, and would bull him around. I think that'd be great fight, but ultimately, Laciar breaks the littler man down. Chang is all wrong for Canto, IMO. Canto doesn't have any kind of power to deter Chang. The Park fights showed how that winding, Korean left with feints and pawing could completely flummox Canto, and Chang was better than Park in most areas. I think he'd confuse Canto, and then out-work him. Clearly. Chang clear decision. Oba is the main match up I can't get a grip of. In theory, Chang can win this. I tend to think that he does something similar to what he did vs Chitalada, where he dances around on the back foot using cross-counters and all sorts of baits from that stylish left he had. Oba's jab is gonna land, and shortly thereafter, so are his power shots. I think Chang can take them, and move on. I'd probably pick Chang on a close decision in a great fight. I don't think any flyweight could go through those five in a sort of round robin without picking up at least one loss. They're too good.
I actually think Yuri is lost versus peak Chang. Arbachakov, similar to Tszyu, can be deadly if you give him the proper distance to operate, but I think Chang is too quick and dynamic, and really gets inside Yuri's wheelhouse and badly outfights him. My opinion of Arbachakov has dropped. I think the gap in class between them is big enough to negate Yuri's size edge, and I question how much of a size edge he would even have. Chang looked devastating at 112 against Alfonso Lopez, for example. In fact, I think Arbachakov's chances against peak Chang are pretty slim.
I agree more with Xplosive on the Chang/Arbachakov matchup, though not as heavily. Chang has the talent/style edge, Yuri a notable edge in punching power. I don’t think he’d hold any significant size advantage. It’s a tough one, but I’d definitely favor Chang if forced to pick.
The only flyweight I see Chang really overmatched against is Harada. I'd give him a chance versus any other.
I don’t see why he’d be overmatched in that one. To be honest, I’ve turned a page on my rating of Flyweight Harada. He was still a physically developing teenager for the entire Flyweight portion of his career. He looked great dethroning Kingpetch, but not so great in the rematch. And we don’t have much else to go on. As a still growing young man, the weight cut had to have been hell on his body by the rematch in Thailand. With that said, he also just wasn’t seasoned enough to adapt to a completely rejuvenated Kingpetch on his A game. Otherwise, he shouldn’t have lost an over the weight bout to Edmundo Esparza (fine fighter that he was) just prior to his title win. He got by mostly on talent at Flyweight, and even that was short lived due to his body hastily outgrowing the division. He put it all together for one night when it mattered most, but one fight at that level is just too small a sample size for him to be rated as a great there, in my opinion. Even in a head to head sense. It was one hell of a sample, though.
