Yes it is.
The main two option routes that Moore had been calling are the post or the out to Gallup, on the outside. And the hook or post to Lamb on the inside. Both of those routes accompanied by a shallow crosser would jet the job done. But, Moore called the option to Lamb too often, and defenses countered it by clogging the middle. Taking away Lamb and the crosser at the same time. So, Moore (finally) adjusted to the clogging the middle strategy, by throwing to our RB's in the flat.
Moore's current play calling, RB's in the flat, is designed to beat the cover two zone. When teams play a lot of man against us we have the advantage with Lamb and Shultz. Lamb can't be covered by man in the slot, and Shultz can't be covered by a LB in a one on one situation. So, Moore has defenses in a pick your poison situation, he just has to keep it up.
