User blog comment:Vazelos3/Coby as a Captain/@comment-8823907-20130611142530

Well i may be wrong but i think that someone like Kong for example will handle the administrative subjects and that Akainu as a fleet admiral is more of a strategy maker and gives the orders to the marines on how when and with whom to attack. Secondly Coby has awakened haki. I dont think any marines that posses haki and are under the rank of VA have been showed (i could be wrong) this gives him great ptential and would secure him a promotion. Also Coby is basicaly Garps student and his actions would have surely come to the attention of the higher ranking marines in charge of promotions, also it could be that Garp gave a good word in for him and certain marines have been impresed by him. Smokre and tashigi for example believed that the fight was pointles after Ace and WB died yet only Coby was wiling to step up against one of the most powerfull fighters in the marines.

Last point. To have a strong soldier under his comand is something akainu has been trying to do since he was promoted, now i dont think that Coby is near the level of a VA but he is very powerfull and there is enaugh room for him to grow and he did not go against the marines orders nearly stated his view so that is it :D These are my thoughts on the matter
