The linebacking crew has had some great games and some not-so-great games.
In my opinion, about 65 percent of the rush defense lies on the shoulders of the linebackers, and they are not succeeding in this aspect of the game.
Giving up a ridiculous 5.2 yards a carry—good for third-worst in the league—running backs are having their way with the Lions, and it is not pretty. They also rank the third-worst in yards per game, giving up 137.6 on the ground and with nine 20-plus yard plays given up.
Taking that into consideration, DeAndre Levy and Stephen Tulloch are actually having great statistical seasons.
Levy is leading the crew with 63 tackles and Tulloch has 52 to go with his three sacks. Bobby Carpenter and Justin Durant have also been nice surprises, playing well when given the chance.
The one nice stat the Lions rush defense has is that they have been great in the red zone. Detroit has allowed only three touchdowns on the ground, good for third-best in the league. Teams can drive down the field, only to be forced to pass once they get close, playing right into the Lions' strength.
Overall, the rush defense for the Detroit Lions needs to improve fast, and it all has to start with this group. If the Lions want to keep winning—especially in the colder months—they can't keep getting gashed on the ground.
With already three 100-yard games in the books for opposing running backs, they need to start locking down and preventing the big plays they have been giving up.
