The Rams starting inside linebacker is a UDFA from Washington in his third year in the NFL. He came into the year with just five starts to his name but now leads the Rams in tackles by a wide margin.
Some of that has to do with the fact that he is a weaker part of their defense. He is not sound metrically by passer rating or PFF grade. The Rams are one of the weaker run defenses in the NFL, and that has to do with issues in the second level.
However, he also has four sacks and eight tackles for loss, which rank second on his team behind Aaron Donald. So, with some downs of an unknown quantity in the middle of the defense you also see a sense of splash plays.
On top of that, Littleton is a player who made his name on special teams and still has 111 snaps on that unit. Littleton blocked a kick that turned into a safety earlier this year.
The Chicago Bears have already been victims of special teams issues this season. They cannot let Littleton get the better of them on either side of the ball.
