Caleb Douglas made his NFL debut on Sunday. He and Chris Bell were the starting wideouts for the Miami Dolphins in the opener against the Las Vegas Raiders. Douglas struggled early. Later, Malik Willis found him for a 25-yard gain. The Dolphins left their most seasoned receiver off the opener lineup. That put the receiving work in young hands. The team went with an unproven receiving corps. That group drew attention as possible waiver-wire adds in advance of the opener. The young group was in the spotlight. Analysts suggested the group could stand out as rookie receivers. Douglas's only reception went on the books for 25 yards.
