AFC South Q&A: What is the state of the division's run defense?

Today's question: The Titans spent a lot of draft resources on their run game -- David Cobb will get carries, Jalston Fowler will work as the new fullback and Jeremiah Poutasi is likely to be the new right tackle. What's the state of your team's run defense as the Titans try to set themselves up to run better?

Tania Ganguli, Houston Texans: Last season the Texans ranked 10th in the league in rushing yards allowed (1,681) and rushing yards allowed per carry (4.0). They were stronger in yards after contact (626) and not as strong in yards before contact (1,075). The addition of nose tackle Vince Wilfork will be important for the Texans' run defense. Last season they played Ryan Pickett in that role, and he might be on call in case of injuries. My biggest question as far as the Texans' run defense will be how they replace outside linebacker Brooks Reed's contribution. Feeling comfortable with the players they have, the Texans did not add a run-stopping, set-the-edge kind of outside linebacker during the offseason. Whitney Mercilus and Jadeveon Clowney have been more pass-rushing outside linebackers in the past.

Mike Wells, Indianapolis Colts: If last season was any indication, the Titans should feel pretty good about their chances to run the ball against the Colts. Indianapolis finished 18th in the league when it came to stopping the run. And the Colts gave up 177 rushing yards the last time they took the field in the AFC Championship Game. The Titans, even before their offensive additions, had success running the ball against Indianapolis. The Titans rushed for 142 yards in their Week 17 loss to them last season. The only difference with the Colts' starting front seven from last season is that Kendall Langford will replace the departed Cory Redding on the defensive end and Robert Mathis or Trent Cole will start over Bjoern Werner at rush linebacker.

Mike DiRocco, Jacksonville Jaguars: The Jaguars were 27th against the rush in 2014, but middle linebacker Paul Posluszny missed nine games with a torn pectoral muscle. The Jaguars have few changes up front in their run defense for 2015. They lost defensive end Red Bryant but replaced him with Jared Odrick. Defensive tackle Roy Miller is expected to be completely recovered from offseason knee surgery by the season opener, but defensive tackle Sen'Derrick Marks is still rehabbing a torn right ACL. Posluszny is back, though he said he's still underweight. One big addition is 6-foot-2, 250-pound Dan Skuta at outside linebacker; he gives the Jaguars a more physical presence at that spot than they had last season.
