Free Agent Breakdown: Antrel Rolle

By Dan Durkin-

What happened: ​The Bears signed free safety Antrel Rolle to a three-year deal worth a reported $11.25 million, with $5 million guaranteed.

How it affects the Bears' salary cap: Chicago entered free agency with about $32 million available, $6 million of which will go toward its draft class. Pernell McPhee's new deal works out to an average annual value of around $8 million, while Rolle's is less than $4 million. Terms of Eddie Royal's deal aren't known, but the Bears still have ample space to sign a few more starting-caliber players.

Player bio bits: ​​The 32-year old Rolle is entering his 11th NFL season. He was selected in the first round of the 2005 draft (eighth overall) by the Arizona Cardinals. Rolle was originally a cornerback before converting to safety in the 2008 season. Rolle has played the last five seasons in New York, where he didn't miss a single start for the Giants.

How Rolle fits the system: ​​Bears defensive coordinator Vic Fangio's scheme plays a lot of press coverage on the perimeter, which requires free safeties to provide deep help with range over the top. He also prefers safeties with interchangeable skill sets, which fits Rolle's playing style. He's displayed versatility, lining up as a box safety, free safety and slot corner for the Giants. His background as a cornerback has allowed him to match tight ends up the seam, but he's also a willing run support player.

Rolle has been a dynamic, reliable safety throughout his career who can be used in a variety of roles in both base and sub packages.
