He was already YC1 before the fruit, the guy was equal to preMera Sabo who was the strongest under Dragon and we saw that the other commanders are not pushovers either since they were enough to help Sabo against 2 Admirals.
Jinbei fightning this dude would require a huge boost and unlike the other SHs, he is already a veteran player in New World. It won't make much sense this kind of boost when his opponent was below Jack, who is/was probably the weakest YC.
