Don't think he was p4p no1, but he was definitely top 10, perhaps top 5 p4p at one point. Definitely should be in the HOF and is at least one of the greatest for his division/s.
I dunno about this "GOAT in his weight division" stuff. He was probably at his very best at light-fly, where he achieved the least. But I think he's an excellent fighter and at one time was a great one. I'm fine with his being p4p #1 for a spell. There will probably be a few passing it about post-Mayweather, that's the way it often goes.
He wasn't a Mayweather/Pacquiao/Leonard/Jones Jr/Whitaker/Duran level talent, but I figured he'd be a Pryor/Arguello/Harada level guy. I guess he's just going to fall a bit short of that and be another Donaire. He'll still be a top 10 fighter of the decade, but on the lower end instead of the upper end. I've honestly never seen a guy drop off that quickly before. He was several levels better just in his last fight with Rungvisai. What happened to him in the last couple of months?
See, this question puts me in a weird position. On the one hand, I've probably followed Chocolatito longer than anybody on this board. Like yes, unavoidably, that must sound very "hipster" of me, but honestly I'm that much of a lighter-weights nerd that even way back in 2008 and 2009 you had a very small handful of international fans including myself going "OMG everybody needs to be on the lookout for Román González, this kid is a p4p beast in the making!" - and through eight years of watching him, even in some performances where he looked a bit closer to mortal than others, I never had much reason to doubt that he was every bit the p4p beast that some of us had built him into with our collaborative hyping efforts. That said, I have, regrettably, not seen either Wangek fight (you may have all noticed that I'm not around much anymore, which does mean there has been a commensurate drop in how much boxing I watch. Barely any, these days, to be honest...) so the results are kind of baffling to me. I've heard mixed things on Wangek vs. González I, some feeling it was a robbery and some that it was a just decision, with people whose opinions are meaningful and respectable to me on both sides of the aisle, but now it seems to be confirmed with a clean as can be knockout (just watched from the bell to start the 4th until the finish on YouTube) that Wangek does have Chocolatito's number. Which is strange, because like I said, having followed him for eight years and roughly two dozen matches, I never caught a whiff of anything to suggest that González would lose to somebody as ordinary as Wangek. And that is the other thing - I have seen plenty of Wangek over the years, and while he's a heavy-handed dude, and while I recognize that his early career losses were due to running a ridiculously, unfairly difficult gauntlet for somebody that inexperienced - I mean, nearing-prime Yaegashi in your ****ing debut? Followed less than a year later by unbeaten prime 16-0-2 (14) Kenji Oba?? WTF?? - he never seemed all that special to me, like he was the one to halt González's progression or keep him from reaching the vaunted Marciano or Mayweather high-water marks. There was always concern that climbing up too high in weight in search of a challenge might be the Nicaraguan phenom's undoing, like Icarus flying too near the sun, but I don't think most of us ever thought his cutoff would be as low as super fly, nor that if he were to lose at super fly it would be to somebody like Wangek. In summation, I'm shook. And I need to watch these fights.
