Concerns about Smith's background have played a role in his evaluation. He was arrested twice for possession of alcohol as a minor and had a positive drug test in 2007, according to The Denver Post.
Smith ran the 40-yard dash in 4.46 seconds, had a 36-inch vertical jump and did 24 bench-press repetitions at last month's NFL Scouting Combine.
Smith allowed just 11 pass completions in man coverage as a junior and senior, says NFL.com analyst Bucky Brooks, who describes the 6-foot-2, 211-pound cornerback as rangy with speed, quickness and athleticism -- smooth and fluid in his movements, showing short-area explosion when changing directions. Brooks believes Smith is ideally suited to play as a "press" corner, and few prospects can rival his performance over the past two seasons.
