Re-signed Haggans provides depth, leadership

Posted by ESPN.com's Mike Sando

The Cardinals have re-signed four of their own unrestricted free agents after Clark Haggans accepted a three-year deal.

The other NFC West teams have each re-signed two UFAs.

Haggans, 32, provides depth and leadership at linebacker. He is also coming off a foot injury that ended his 2008 season early.

The chart lists the Cardinals' linebackers from oldest to youngest.

Chike Okeafor's ability to stay healthy proved important for Arizona last season. He started 16 games after missing the 2007 season. He previously had not missed a game since 2001.
