Hes right.
Croc jinbe Iva not running from law
Nor is law soloing yami teach and his crew
Imo Law can do those things. As I said, there's no proof. Law is obviously not gonna get a chance to show if he could have done it or not. So all we can do is speculate based on our biases and what we've seen. But,
Law is a pirate worth 3 billion. That's more than BB had when he became a yonko. And Law has the clout of being a major part of the team that took down 2 yonko. So if Iva, croco and jinbe had that info, they would run faster than they did against Magellan.
And Magellan negging yami teach, that's a very situational thing. They were in a cramped super prison. That like the perfect place for Magellans fruit to wreak havoc.
If y'all are scaling shiryu to Magellan, then put Magellan against Law and see where that goes. Law(even pre skip Law tbh) completely negates most of Magellans tricks. He can just slice up Magellan from far away and it's gg.
