At 5'11" and 180 pounds, Sheffield has a fantastic combination of quickness, agility, length, speed and pure cover skills.
He has a quick and tight backpedal, possesses loose hips and easy movement skills in space. With his quick hands and agility in tight space, the 5-star cornerback can be a menace in press-man coverage. Sheffield plays with solid anticipation in off-man coverage, where he can easily copy and mirror the movements of receivers.
In zone, Sheffield has great range and awareness. He does a solid job of passing receivers off to other defenders, while recognizing and picking up other threats quickly in his area.
The Texan displays terrific short-area quickness, which allows him to drive and close on balls underneath in a flash. With his 4.36 speed in the 40-yard dash—says Scout.com—Sheffield has no problem carrying receivers deep downfield. He has no problem staying stacked on top of them, either.
Sheffield also has return value on special teams.
