Lucci is easily YC1. Pushing Zoro to a high diff fight isn't a bad look.
My problem w/ Zoro vs. Lucci is that it logically shouldn't do much for Zoro as a fighter.
Zoro still has a long way to go before he reaches Mihawk's level.
Lucci would have to be not just arguably stronger than King, but outright and obviously stronger than him to push Zoro's growth.
There's just such a huge disparity between who Mihawk and Rayleigh are (as in, the benchmarks for EoS Zoro) and who Zoro is right now. Or at least, that's how it seems based on Zoro's track record of opponents and his prestige.
