Has Inoue surpassed Harada?

No.

But if Inoue becomes Undisputed in 3 weight classes, he will be the GOAT.

 

Yes he is. Pac got destroyed by guys down there that inoue would have left in a coma. He would've beaten the **** out of pac at 112 or 115 or 118 or 122.
But no he can't be the goat because there's no big name fighters down there and there's already a natural bias against fighters below 135.

 

Inoue is certainly on a roll. If he becomes undisputed at 122 and 126 he is in the GOAT conversation. He seems to be unbeatable.

 

You'll never be the GOAT fighting at those weights it is what it is. Bigger fighters are always going to be rated higher historically.

 

Inoue has way surpassed Harada. The better I understand their careers, the more I legitimately don't understand how they could be compared.

Harada went 8-7 (1 KO) vs Ring rated fighters, though according to most accounts, he should have been 9-6. Inoue is 18-0 (16 KO) vs Ring rated fighters. Harada went 3-4 (1 KO) vs title holders, Inoue is 12-0 (10 KO) vs title holders. Only in HoFers does Harada have a statistical edge, being 3-1 (1 KO) vs HoFers. Inoue is currently 0-0, although 2-0 (1 KO) is almost certain for the Donaire fights.

Inoue is a 4 division champion, from 108 to 122 excluding 112. Harada is a 2 division champion, at 112 and 118. Both are undisputed in 1 division, 118. Harada was only unified at 118 although he fought in the 2 belt era. Inoue has been unified in 2, 118 and 122.

It basically comes down to if you think Jofre is THAT great, and I think that is terrible weighting, personally.

 

Henry Armstrong was rated pretty high historically, as was Pac, Floyd, Pep but you're probably right.

 

I understand what you are saying. Inoue's best win was an old Donaire. Today he dominated a very good champion and looked fantastic doing so.

 

It depends on your criteria.

Harada beat Pone Kingpetch who is generally regarded as a top 10 Flyweight of all time & Eder Jofre, who is probably most commonly ranked as GOAT at BW & is usually on the fringes of the top 20 p4p fighters of all time, x 2, both whilst in their prime. Harada was the only fighter who ever beat Jofre in his 78 fights.

Inoue has already won titles in more divisions than Harada (though, bear in mind there are 68+ "world champions" across all weights today, relative to the 10 in Harada's day), already beaten more ring magazine ranked contenders & unlike Harada, is yet to lose. On the flipside he hasn't beaten a prime fighter as great as Kingpetch, let alone Jofre.

I suspect that Inoue is even better than Harada, relative to their eras (and that is a huge compliment), but whether you consider him greater depends on whether you go for fewer but better quality wins over contenders of Harada, or the more but lower quality wins of Inoue. Inoue is of course active & will no doubt go on to add to his win resume & achievements.
