This is my perspective on it
-Dodson x 2 are good wins (dodson to this day has only ever lost to mighty mouse in this weight class)
-Joe B x 2 are good wins(Joe b fought for a title twice after mouse left)
-Horiguchi is a good win (young, but Flyweights are going to be young. Just how it is)
-Bagautinov is a good win (undefated and roiding)
-Cejudo is a good win (undefeated, Olympian, Future double champ)
-that's 7 quality title defenses
-The others, while they are not the best competition, mighty mouse did not let those fights be even remotely close. he finished them all empathetically and absolutely styled on them
-He lost the title in a split decision that many think he won, his record could read Cejudo x2 as well
-He's still winning fights today
Personally, I'd not have Khabib (not a top 10 goat) or DC on the Rung Below jones, Mighty mouse and GSP.
I think the last time I tried to do a GOAT list it was
1. GSP
2. Jones
3. Anderson
4. Fedor
5. Mighty Mouse
6. Aldo
7. Khabib
8. DC
After that Izzy, Holloway, Volk, Stipe, Usman, Cruz, Hendo, Nog, Hughes, Cejudo, Penn etc. I'm not sure how to put'em. Fedor is an odd one too, I could see him below everyone on that top 8 list depending on how you see it. I think Islam will be in this equation soon, if he beats Poirier and Arman II, if he goes up and wins 170lb...dudes probably top 4. OMalley if he can beat Merab and then the winner of Sandhagen/Umar he can very likely get a spot on the top 10-15 already too. Topuria is similar for me, if he faces Max next and wins and then Evloev? He's top 10-15. But we will see.
Like I said, depending on how you see Dodson and Benavidez. To me? Dodson would be a 50-60% win rate vs the top 10 of today and some of the prospects, even in his prime at 125. Benavidez I feel somewhat similar about, he was good he'd be a top 10 guy but not someone who made waves and would need a streak vs the right guys to even get a title shot....but also a tough night for most guys. Bagautinov didn't age well at all, roiding means nothing, Bagautinov has very few good wins in his entire career. Kyoji is a huge win but he was super green, 23-24 was too young FOR HIM, he and his gym asked the UFC to decline the title fight and they said he'd never get another opportunity if he turned it down and that he had to take it...the division has evolved a lot because he didn't exist until midway through Mighty Mouses career.
Eras do matter and how wins age do matter, there's a difference between beating Jake Shields when he was on a 14 fight win streak, top 10 p4p, had wins over guys like Okami, Hendo, Condit, Lawler, Sakurai etc and then Jake getting kinda older and falling off...that win aged fine, because Jake was a great and in his prime and then fell off but his wins and who he was, was undeniable. Bagautinov was decent and had a couple good wins vs Eliot and Lineker but he did get exposed...he wasn't the Worldbeater we had hoped...win didn't age well, turned out he wasn't all that.
Anyways, not really arguing just sharing.
