The Saints have spent much of the last two offseasons building up their secondary and making sure they have the personnel to improve in coverage. [caption id="attachment_6822" align="alignright" width="300"]AP AP[/caption] Many of those boxes are checked. They're set at safety with Jairus Byrd and Kenny Vaccaro. They have their corners in Brandon Browner and Keenan Lewis. The only spot that really remains is who covers the slot. New Orleans has taken steps to address this position by signing Kyle Wilson and drafting P.J. Williams, and has some internal options in Brian Dixon and Terrence Frederick, but this spot isn't locked down like the others in the secondary. Wilson had his moments in New York, and Williams has the potential to do great things, but neither player is a lock for the job. Wilson could struggle in this defense, and it's unknown how quickly Williams will get up to speed. It's not uncommon for rookie cornerbacks to struggle in their first year. If any doubt remains about this position, Kyle Arrington, who was released by the Patriots on Monday morning, could be an intriguing option for New Orleans. While it would take some juggling to create the cap space, Arrington would likely be willing to play for minimum $870,000 salary. If not, maybe $1-1.5 million gets it done. It wouldn't take much and it could pay off huge for a defense that either has a lot of depth at this position or is still in search of a sure thing. If stats are to be believed, Arrington ranked 18th in quarterback rating against (83.9) among cornerbacks who spent 25 percent or more of their snaps covering the slot last season. Wilson, meanwhile, was 46th (112.4). It's also worth noting that in two games against the Colts last year, Arrington gave up two catches on seven targets to T.Y. Hilton, who is one of the best slot receivers in the NFL. For what it's worth, Vaccaro ranked seventh with a 61.6 quarterback rating against when covering the slot. It's possible that Vaccaro could figure back into the mix there, but if the Saints want to free him up to do other things, finding the right guy to cover the slot will be paramount. Maybe the answer is already on the roster. Maybe it isn't. But as organized team activities inch closer, this remains one of the last unanswered questions for New Orleans' secondary.
