Earlier in the week I looked at the first to 10th and 11th to 20th defensive prospects in the 2012 draft. Today, I will look at the 21st to 30th prospects.
21. Mark Barron, SS, Alabama: Barron will compete with Ray Ray for the No. 1 SS in the draft. Right now, Ray Ray is ahead of him but Barron will still go in the first or second round.
Follow the jump to see 22 through 30.
