While Duck’s size goes to waste as a run defender, he’s more than capable of utilizing it to aggressively contest throws in man coverage. He’s patient to time up jabs from press and does a nice job of bird-dogging the route from trail-man, but speedsters can run away from him as the route progresses. Duck lacks the premium athleticism and closing burst to play from off coverage and still create ball challenges. His size and peskiness at the catch point are tempting, but there might not be enough of the total package in place for him to make a roster.
