The Dallas Cowboys offense was one of the very best in the NFL last year. Much of the group has returned for the 2024 season so things figure to be similarly solid. Dak Prescott is at quarterback and CeeDee Lamb will presumably be in the fold as the top wide receiver provided he returns to the team amid contractual dissatisfaction.
Lamb has been absent throughout voluntary workouts and OTAs up to this point, but given that the summer has just begun there has not been any high level of concern. It is not quite standard operating procedure for these things to occur but they are not uncommon.
