If Buggy attacked a Yonko, got crushed and forced to serve undr him, would you consider he has "luck, power, grit, willpower", and would you find Morgan's claim of Buggy potentially becoming PK believable?
The majority of the Supernovas were proven to be absurdly far from reaching Yonko level. Kidd Apoo and the rest have willpower and balls, but at the end of the day they are mere nuisance for Yonkos. And yes they have luck, the luck that the Yonko they attacked actually didn't finish them off. Takes more than that to become PK.
Like, i do believe we'll see more from them, they'll have their role to play. But inside the OP world, how can Morgan even believe someone like Kidd is close or has a chance of becoming PK, now that his alliance got utterly destroyed by Kaido and he's now imprisoned and the rests are slaves? How is that believable?
The only one going far enough to become a potential threat is Luffy, Luffy alone. And again, we didn't see a lot from Zoro and Law yet, and we know Urouge could do something. But the rest of them? No way.
Had Morgan said "i have the feeling Strawhat Luffy could become PK" i'd say alright, fair enough. Considering what he has shown. But including the rest of the Supernovas is absurd.
They are absolutely not the closest to becoming PK, considering one has to possess the Road Poneglyphs to attain Raftel, and aside from Luffy (who got his hands on Big Mom's), nobody came even close to obtaining a Road Poneglyph, let alone 4 of them.
We don't know if Morgan actually knows about Road Poneglyphs though, but if he doesn't it's yet another proof that he has no way to imply anything for sure. I'm not that sure he "knows more that we do".
