That's the understatement of the century.
The Companions clearly were the result of a rush last minute job and terrible pacing. Also still wondering why their werewolf status isnt an open secret, since guards can literally tell you you smell of wet fur if you became a werewolf.
Jorrvaskr must stink of dog/wolf. They should have had at least some wardogs all around the place to obscure this obvious tell.
We never learn who the Silver hands are. Why they arent just Vigilante of Stendar, instead of a bandit faction with silver swords.
