**UPDATED 1/26**
1) Dre Kirkpatrick, Alabama

Kirkpatrick in my opinion plays more like a safety, and it actually wouldn't surprise me to see a team that is ok at corner but needs safety (maybe Eagles, Cards, Bengals, Titans) take him to start at safety in the short run. 

2) Mark Barron, Alabama

Barron is the best pure safety in the class and should be able to solidify his top-25 status with a good combine.

3) George Iloka, Boise State
Iloka has been a fierce player for Boise State the last few years, but the reports on the 6'4 kid are that he is one of the most polished defensive backs in the draft.
4) Marekelle Martin, OK State

Martin is possibly the best free safety prospect in the draft, and he should go in the top-60 picks.
