Sean Lee and Bruce Carter will determine the success of the Dallas Cowboys' new 4-3 defense. Even though the Cowboys have switched to a scheme featuring an extra defensive linemen, their two young linebackers will determine its success.
Wily old coordinator Monte Kiffin places a lot of coverage responsibility on his linebackers. They are charged with covering short, underneath areas and deep zones.
Kiffin demands superior athletes at the position. Fortunately that's exactly what he has in Lee and Carter.
If the pair stay healthy they are arguably the best tandem of young linebackers in the NFL. Both possess sideline-to-sideline speed and a knack for making plays in pass defense.
Kiffin's scheme will rely on their playmaking talents. Carter will have one of the most important roles as the weak-side linebacker.
In Kiffin's 'under' fronts, two defensive linemen are usually stacked over on the weakside. That keeps the weak-side 'backer covered up and free to make plays.
