I would say that, sure, it's entirely possible that not much else happens the rest of this offseason. Perhaps even probable, I don't know.
But outside of a handful of teams, there really hasn't been a ton of activity for most teams at this point so I'm not sure it's accurate to suggest that they aren't trying to do things or that they are clearly done trying to improve at this point. The market is just kinda slow and will probably be that way until some of the bigger pieces come off the board.
