It could be argued the Titans got their money’s worth on defense in 2012. Only one team allocated fewer dollars on that side of the ball than the Titans did last season, according to a recent report of all 32 NFL teams by The Guardian. So it shouldn’t have been a huge surprise that Tennessee finished last in the league in points allowed while giving up a franchise-record 471. The Titans have made upgrading the defense a priority. But will they pay up for veterans in free agency? Or will they look for impact players in the NFL Draft? “We know we have to find leadership, and that is important,” coach Mike Munchak said. “We have some young players but could use some veteran-type players at positions, like linebackers. … We’d like to add some guys on the defensive line, veterans or rookies. … We’ll likely find a mix of guys to get it done.” The Titans spent $38 million on defensive players in 2012, compared with $69.1 million on offensive players, according to the report. Only the Raiders spent less on defense, and only the Buccaneers spent more on offense. The Super Bowl champion Ravens spent $64.0 million on defense, $49.1 million on offense. Cornerback Jason McCourty, defensive end Kamerion Wimbley and safety Michael Griffin were the highest-paid starters on a young Titans defense last season. But veteran Will Witherspoon, who lost his starting job to rookie Zach Brown, collected the biggest salary on that side of the ball.
