Probable overreaction - Why have we only added 1 new player on Offense.

I know our Defense was historically bad last year, and we managed to bring back all 3 of our pending OL, along with getting Tommy back. However, besides adding Rico to the offense, we have not added any other new FAs on that side of the ball. I don't mean swinging big but even just an experienced vet like Elijah Moore that would fit a need and still fit the teams criteria of a younger vet who's best FB should be ahead of them.
