Here are the top five defensive back prospects (with projected round):

Ha Ha Clinton-Dix*, S, 6-foot-1, 208 pounds, Alabama (first): Clinton-Dix quickly lived up to his billing as the nation's top-rated safety out of high school. Clinton-Dix was named to the All-SEC first team in 2013. NFL.com combine profile comment: "Lean, athletic, physical, instinctive free safety with starter-caliber range, coverage skills and tackling ability."

Darqueze Dennard, 5-10, 200, Michigan State (first): As a senior Dennard, from Twiggs County, was a unanimous first-team All-American and winner of the Jim Thorpe Award as the top defensive back in college. NFL.com combine profile comment: "Big, strong, athletic, instinctive press-man corner who elevated his game as a senior."

Calvin Pryor*, S, 5-11, 207, Louisville (first): Pryor was the best player on Louisville's highly ranked defensive units over the past three seasons. NFL.com combine profile comment: "Perhaps the most explosive hitter in this year's crop of safeties, Pryor is a big, physical hammer in the run game, bringing the ability to intimidate and erase.

Justin Gilbert, CB, 6-0, 202, Oklahoma State (first): Gilbert has plus-size and speed (4.37 seconds for 40 yards) and is dangerous with the ball: He returned two of his six interceptions in 2013 for touchdowns and scored six times on kickoff returns over four seasons. NFL.com combine profile comment: "A big, fast, athletic, man-cover corner capable of locking down receivers and creating big plays in the return game."

Jason Verrett, CB, 5-9, 189, TCU (second): In spite of his relatively small frame and a shoulder injury, Verrett reportedly bench pressed 225 pounds 19 times at TCU's pro day. NFL.com combine profile comment: "A tough, scrappy, undersized nickel back with potential to emerge as a No. 2 cornerback."
