Next season will be Pagano’s third as the defensive coordinator. The San Diego Chargers have re-signed defensive coordinator John Pagano, a league source told ESPN NFL Insider Adam Schefter. The Chargers lost one coordinator this week. Pagano and the defense started slow in 2013 but turned up the pressure as the season continued. Chargers.com: Is there a certain game that you will remember most from this past season? The 46-year-old took over as coordinator after a 2011 season in which the Chargers allowed a 49.2 percent third-down conversion rate, worst in the NFL since 1995. During a five-game win streak that ended the regular season and bled into a wild-card win versus the Bengals, San Diego had a 32.1 percent rate on third down.
