And Yassop, Roo, and Beckman are all stated to incredibly have strong haki.
So you can assume hard COA goes to Yassop and probably speed as well. Heck given that haki is the RHP, we can probably assume his might be harder than Katakuri’s.
So even if he’s not stronger than Kuri he’s still obviously in the same tier, which again implies Beckman is a bit above.
