To be fair, no one thought Oda could do such a mistake. Rear Admiral Coby was actually believable at this stage for someone who is bound to become an admiral, but now it just went back to my original opinion Coby will only reach admiral lvl during the epilogues
He stands no chance against Hancock at this stage, but i secretly hope to turn out to be wrong and he play some part at least
What's for sure though is that it's implied Hancock is in danger, maybe due to the SSG hype though
