One person who is not on the list is Mike McKenzie. The former Packers corner decided to return to the Saints. McKenzie was more of a man-to-man player anyway so might not have fit the Packers' plans. McKenzie, 33, played in seven games last season for New Orleans.
Scout.com NFL analyst Adam Caplan offered four veterans capable of fitting the Packers' defensive scheme.
Fakhir Brown (5-11, 195): Brown, 32, would be in his ninth NFL season but is playing for Florida in the UFL. He started 11 games for the Rams last season, with one interception. He's picked off 11 passes in his career, including four in 2007.
Eric Green (5-11, 196): Green, 27, spent his first four NFL seasons with the Arizona Cardinals, starting 33 games and intercepting two passes. He worked out for the 49ers recently. He was cut by Miami at the end of training camp because of the superb play of rookie Sean Smith. Brown was a third-round pick in 2005 out of Virginia Tech. Of all the available corners, Green offers the best combination of youth and experience, but he struggled in Miami.
Brian Kelly (5-11, 193): Kelly, 33, would be in his 11th season. He played 11 games for the Lions with 10 starts last season but was cut late in the year. He has 22 career interceptions, including eight with Tampa Bay in 2002.
Patrick Surtain (5-11, 195): The 33-year-old Surtain would be in his 11th NFL season. He was a full-time starter from 2000 through 2007 before playing in eight games (with two starts) for Kansas City last season. The three-time Pro Bowler has 37 career interceptions.
