Patrick Robinson: B-
Patrick Robinson is Dr. Jekyll and Mr. Hyde reincarnated as a starting NFL cornerback. At times, Robinson is a top-five type corner with great ball skills. Other times, he is being burnt crisper than toast left on the sidewalk in July heat.
Robinson was pegged the No. 1 corner this season when it became obvious that Jabari Greer was no longer an elite player due to injury and age. Robinson truly was decent at times. But there were several other moments burned in the memories of countless Saints fan which they'd love to forget.
Robinson can and likely will improve. He is going to have to, as he is now the Saints' best corner.
Corey White: C+
For a rookie no one had ever heard of going into the 2012 NFL draft, Corey White had a strong rookie campaign. Sure, he was burned many times over early on in the season, but he showed improvement with each game.
By the time he left the lineup with a knee injury, his improvement and value to the secondary became obvious. Upon inserting Johnny Patrick into the lineup as a rotation corner, the Saints' secondary suffered mightily. White was a consistent cover guy who came up to hit guys when given the opportunity.
Luckily, White will be back in 2013. And he should start opposite Robinson.
Jabari Greer: C
When fully healthy, Jabari Greer was solid in 2012. But he was beaten by average receivers with regularity, unlike at any time in his New Orleans' career.
Greer did have a few beautiful interceptions which helped the teams' case as a solid defense (don't buy into the lie of giving up yardage makes a unit awful) at the end of the year.
Going forward, Greer would help the squad by taking a demotion to nickel corner. In such an adjustment, White would move to the nickel spot, and Greer would continue to play outside, at least most of the time.
Elbert Mack: B-
Elbert Mack must have been cut and re-signed five times by the New Orleans Saints in 2012. Yet, in the second half of the season, he was the teams' most consistent corner. Though he was beat on occasion, Mack showed great ball skills and overall coverage skills.
Mack should return to New Orleans to give the team a solid four-man unit at corner (though one player from the safety quadrant could be added to it, in my opinion).
