Chyl Quarles, Wake Forest, S: Quarles, who started 32 games in his college career and notched 239 tackles and two interceptions, figured to get drafted at some point Saturday. When he didn't, the Ravens were more than happy to give him an opportunity. He has decent size (6-foot-1, 210 pounds) and good ball skills, but the knock on him is his instincts and he isn't as sure-handed of a tackler as teams would like. Still, he led the Demon Deacons with 101 tackles in 2011. After losing both Haruki Nakamura and Tom Zbikowski to free agency, the Ravens are thin at safety, which should benefit Quarles, as will his special teams skills.
