Sheffield is a smallish slot receiver with the speed to challenge defenses on all three levels. He plays fast and has the ability to uncover at an even higher rate over the first two levels with improved route work. In terms of his ball skills, he vacillates between impressive contested grabs and disappointing focus drops. Sheffield’s explosiveness and punt-return potential give him a shot as a backup slot, but his lack of size could limit the amount of suitors willing to give him a long look.
