Tavon says that he wanted the ball in his hands. Which makes me believe that he would have returned the ball if it was his choice to do so. Between this and the fact that film shows a running play was called, despite Garrett saying that a RPO was called with Dak having the option to throw or keep it to himself, is proof that Garrett is intentionally trying to be misleading to save himself and is throwing players under the bus to do so.
If this team loses most of their remaining games and missing the playoffs, I can see them turning on Garrett or Garrett losing the locker room, after blaming the players to save himself. All the more reason for him to be fired.
