Caleb Douglas made his NFL debut on Sunday. He and Chris Bell began the game at receiver for the Miami Dolphins in the season opener against the Las Vegas Raiders. Douglas struggled early. Later, Malik Willis got the ball to him for a 25-yard gain. The Dolphins held their most experienced receiver back for the opener. That left the receiving duties to a young group. The team went with an unproven receiving corps. That group generated interest as potential waiver-wire pickups in advance of the opener. The young group took center stage. Analysts suggested the group could stand out in a rookie receiving class. Douglas's only reception went on the books for 25 yards.
