Many people desperately want the Lions to upgrade the cornerback position. It's the war cry of every Internet message board and comment section for the last few years.
Along with Slay, the Lions do have some potential to improve from within. Third-year corner Chris Greenwood has a real opportunity to prove he can be a bigger part of the solution.
Although he's done little with them in his first two campaigns, the Albion product has a lot of desirable physical traits. At 6'1" and 193 pounds, he's got the size to tantalize.
His 4.41 40-yard dash, 43" vertical and 11'2" broad jump from his 2012 pro day display his incredible athleticism.
Unfortunately, his game was very raw. In fact, he showed so little progress that the Lions waived him just before last season started, per Dave Birkett of the Detroit Free Press.
However, after a brief stint in Dallas, it appears Greenwood returned a new man. Finally active for the final two games in 2013, Greenwood earned a plus-2.3 rating from PFF in 67 snaps. That blows away the likes of Chris Houston, Jonte Green or Bill Bentley.
It's that sort of promise that lends hope that the rangy former fifth-rounder can help solve some of Detroit's chronic secondary issues.
One of two things is likely to happen with Greenwood going forward. He's either going to make a big jump and earn the third corner spot, or else he'll no longer be a Detroit Lion come September.
