Where things stand: Texans defense

The most high-profile move the Houston Texans made this offseason was signing nose tackle Vince Wilfork.

It was a shift from how they handled last season, when Houston mostly hung back and let the market settle before making some lower-profile signings that wound up being key components to a defense that ranked third in the league in yards allowed after their bye week.

Let's take a look at where the Texans' defensive roster stands now.

Defensive end: J.J. Watt, Jared Crick, Jeoffrey Pagan, Keith Browner

Notes: No big changes here to a unit that didn't really need big changes. Pagan was a sixth-round pick who started to get it late last season. I'll be watching his growth here through the offseason.

Defensive tackle: Vince Wilfork, Louis Nix, Tevita Finau

Notes: Wilfork's addition will bring experience and strength to this position. They had a solid player in Ryan Pickett here last year, but Wilfork actually brings relative youth (he's two years younger than Pickett) and the five-time Pro Bowler will have a lot to draw on to teach 2014 draft pick Nix.

Linebacker: Brian Cushing, Jadeveon Clowney, Whitney Mercilus, Mike Mohamed, Justin Tuggle, John Simon, Max Bullough, Jason Ankrah, Kourtnei Brown

Notes: This unit has three first-round picks. Outside linebacker Brooks Reed, their starting strongside linebacker for the past three seasons, departed in free agency. Akeem Dent, who started beside Cushing, is still on the market and has reportedly been in touch with the Texans. The Texans could be OK at inside linebacker with their current roster, but I think it's a position they'll examine in the draft.

Cornerback: Johnathan Joseph, Kareem Jackson, A.J. Bouye, Darryl Morris, Josh Aubrey, Andre Hal, Jumal Rolle, Charles James

Notes: Joseph is still here with no alterations to his contract. His departure has been floated the past two seasons, but the fact remains his skill set is still valuable enough to the Texans that they can't afford not to have him. They re-signed Jackson in free agency and have Bouye, a developing young corner, in the fold.

Safety: Rahim Moore, D.J. Swearinger, Lonnie Ballentine, Terrance Parks

Notes: Moore was one of the top safeties available in the market this year and effectively replaced Kendrick Lewis. Lewis did have an offer from the Texans, but it was not a starter's offer, which is what he was for the Texans last season. They likely made the offer with their pursuit of Moore in mind. Lewis signed with the Baltimore Ravens.
