Yeah absolutely, Oda has been making the Marines look pretty awful post TS for the most part. In hindsight I'm glad Green Bull is pro Marine/WG at least, having both he and Fujitora be Anti-WG and even "good guys" along with Aokiji already stepping down and "betraying" the Marines and WG at least publically is sheer overkill and redundant.
I Just hope Green Bull is more nuanced than this and that personality we saw of his back at Reverie hasn't been scrapped. It would be cool if he's only like that with his fellow Marines and the WG naturally.
They really need more Admirals too, they have at least 2 Admiral worthy candidates and if they could find these 2 over the TS, who's to say they couldn't find more too?
Plus with someone like Akainu in charge, I expected him to forcibly make the Marines train and gain extremely hard to make up for what happened at Marineford especially too.
