NFL Network insider Jason La Canfora reports that Steelers LB LaMarr Woodley is battling a hamstring injury and is on the sideline against the Dolphins. Woodley is questionable to return.

NFL Network insider Jason La Canfora took a Thursday spin “Around the League” with host Rich Eisen on “NFL Total Access.”

With so many teams playing the 3-4 defense these days, college defensive ends are often being asked to run some outside linebacker drills at their pro days.

The NFC is first up for practice Thursday, and the players have already changed and are getting to position meetings. Among them are Vikings RB Adrian Peterson and Falcons WR Roddy White, who missed the first day of practice yesterday as a late addition.

Pittsburgh’s offensive line getting overwhelmed on third down, in four-and-five receiver sets.

Ben Roethlisberger’s sack altered field position and changed the early tenor of the game.

The Steelers return 20 of 22 starters, which makes them strong contenders to repeat as Super Bowl champions. They still have Dick LeBeau running the defense, and his players call him “The Wizard,” which reflects the schemes and creativity he brings. The offense still has Ben Roethlisberger under center and returns RB Rashard Mendenhall after a season-ending shoulder injury last year.

The bar has been set with the recent success of the Cowboys, Patriots, Ravens, Chargers and Steelers’ 3-4 defenses, and now it has become vogue to run the scheme. As many as 15 teams are either making the switch or infusing elements of the 3-4 defense, but can they be successful? Here are five key ingredients that will make or break the transition.

Earlier in the week, a Pittsburgh writer asked Chargers QB Philip Rivers what he thinks about the fact there are a lot of players and fans who just don’t like him. Rivers said he didn’t understand it because from his experience, he gets along with everyone and that people misunderstand him when they see him and don’t hear what he’s saying. I don’t have to hear what he just said to Steelers LB LaMarr Woodley after being sacked to know it wasn’t nice play.
