Cowboys quarterback Dak Prescott recently said he doesn’t know “if any team in the league necessarily needs a No. 1 receiver.” He better hope the Cowboys don’t need one. The Cowboys insist their lack of a No. 1 receiver is overblown. “As far as this locker, to ourselves or in the meeting rooms, we don’t talk about that at all,” said receiver Allen Hurns, who signed with the Cowboys as a free agent.
