I do not think Loomis is done shaping the offensive side of the ball. RB was not even addressed and Kamara will most likely miss time and Ingram is at the backend of his career and only bringing in Abrams make you feel like he was hand picked but I'm sure the Saints are still looking to address this position along with WR.
Honestly given the amount of good backs in the draft I expect some good rookies/vets to find themselves looking for work as the rosters slim down in the pre-season.
Its not ideal, but given the guys available now, and the limited cap space to add players, that may be where we snag our depth.
