The Tennessee Titans have signed defensive coordinator Jim Schwartz, who was a candidate for three head coach vacancies over the past month, to a two-year contract extension, ESPN.com has confirmed through league sources.
Financial details of the extension were not available. Schwartz's previous contract with Tennessee had expired.
A 13-year league veteran, Schwartz presided over the resurgence of the Titans' defense in 2007, as the unit rose to a No. 5 overall statistical ranking after finishing dead last in most yards surrendered in 2006.
Schwartz, 41, holds a degree in economics from Georgetown University and frequently relies on computer analysis to work up defensive game plans. An avid chess player and blessed with an analytical mind, he has taken the baseball book "Moneyball" and attempted to apply its principles to football.
A high-energy coach, Schwartz is a fiery leader for whom veterans enjoy playing, and early in his career he worked for current New England coach Bill Belichick.
