Morning links: Front seven a weakness?

Good morning. Mike Tanier of Sports on Earth ranks the Chargers' defensive front seven as the second-worst in the NFL. According to Tanier, the Cowboys have the worst defensive front seven in the league. The St. Louis Rams have the best.

Tanier: “Run defense was a bigger issue than pass rush for the Chargers last year. Opponents converted 73 percent of 'power' situations (26th in the NFL) and the Chargers stuffed just 16 percent of opposing rushers (27th). The defense allowed few long runs, which means that opponents averaged 4.6 yards per attempt by gouging out consistent four-to-five yard rushes. Nose tackle Cam Thomas (now in Pittsburgh) will be replaced by Sean Lissemore, a former Cowboys prospect coming off a shoulder injury. If that's an upgrade, it's a pretty minor one.”

ESPN NFL Insider John Clayton writes in his weekly mailbag that he does not expect a change in San Diego’s offensive philosophy with the addition of Donald Brown, and that he provides insurance if Ryan Mathews leaves in free agency next year.

According to Rick Gosselin of the Dallas Morning News, the Chargers lost 52 game starts from starters due to injury last season, 13th most in the NFL.

According to Football Outsiders, the Chargers had the second slowest offense in 2013. Seattle, San Francisco, Carolina and New Orleans also took a methodical approach to how they operated on offense.

Greg Gabriel of the National Football Post lists Chargers outside linebacker Jeremiah Attaochu as a rookie breakout candidate for the upcoming season.
