Kyle Wilson, Boise State
Wilson leaps to the top of these congested ratings. This is a terrific group of cornerbacks in Mobile, and Wilson (5-foot-10) was the best on the field on Wednesday. He won the lion's share of his matchups against Cincinnati's Mardy Gilyard. Perhaps his best coverage of the day came in a one-on-one drill, when quarterback Tyler Canfield simply sat in the pocket with nowhere to throw the ball before the coaches blew the play dead.
Devin McCourty, Rutgers
The North's coaching staff (Detroit Lions) got on McCourty for not looking for the ball on a deep reception to Taylor Price. That misstep notwithstanding, the 5-foot-10 McCourty has all the tools to be a starting cornerback, from athleticism to physicality. This wasn't his best day, though.
Patrick Robinson, Florida State
Robinson (5-foot-11) is smooth, athletic, is used to playing man coverage and isn't afraid to get physical. On Wednesday, though, not enough of that showed up. He was generally in the vicinity but not close enough to make a play. It looked like he took a dive when beaten at the line of scrimmage while allowing a touchdown on an "in" route.
Chris Cook, Virginia
At 6-foot-1 1/2, he's got ideal size for the position, especially in this age of big receivers. Plus, he's got arguably the best ball skills. He had a nice interception at the sideline, showing anticipation and good footwork to pick off a weak throw from Tony Pike. Question is, will teams think he can run well enough to play corner in the NFL? Looks like the answer is yes.
Brandon Ghee, Wake Forest
Ghee (5-11) went from unranked to high up on this list after dominating the individual drills and one-on-one matchups. Ghee seems to be getting more comfortable with every practice. While McCourty and Robinson were oblivious to long balls coming over their head, Ghee showed good recognition. Veteran NFL cornerbacks often lack that trait.
Jerome Murphy, South Florida
At 6-foot, Murphy has the requisite size, and his 32-inch arms are the longest among the cornerbacks (other than Kentucky's Trevard Lindley), which gives him extra length. He made a handful of good plays on Wednesday and is really physical at the line of scrimmage. He about knocked Joe Webb on his butt at the line of scrimmage on one play. He also gave up two touchdowns on well-placed balls in a red-zone period.
Perrish Cox, Oklahoma State
The 5-foot-11 Cox had easily his best day with a pair of interceptions late in practice. On the down side, he was playing bump-and-run and got toasted at the line of scrimmage by Shay Hodge.
Nate Allen, South Florida
As good as the cornerbacks are, the group of safeties leave plenty to be desired. The best of the bunch is the 6-foot-1 Allen, who does just about everything well. Like the rest of this group, though, he's been susceptible to giving up the big play by letting receivers get behind him. On the plus side, though, he's athletic enough to cover, which is a must for a safety in today's NFL.
Harry Coleman, LSU
What makes Allen such a good prosect is his coverage skills. Coleman, on the other hand, is more of a traditional safety. Coleman seems to play bigger than his 6-foot-1, 206-pound frame, and he really made his presence felt as an in-the-box defender on running plays.
Taylor Mays, USC
After a great Monday, the 6-foot-3 Mays has just fallen off the face of the earth. You barely notice him half the time; it's not like he's playing poorly. Some team will take him early because they'll love his measurables and their coaches will think that they will be the ones that will bring out Mays' best, but his lack of impact on this stage is perplexing.
