Chicago Bears
Alshon Jeffery (Wide Receiver): The Rams have given up the 4th fewest fantasy points to wide receivers all season long and this should be no different in week 10. He will see 15 plus targets a game so he is a realistic option this week but it is wise to lower your expectations against such a stout defense.
Jeremy Langford (Running Back): The Rams have given up 5 rushing touchdowns in 8 games and are holding opposing running backs to 3.8 yards per carry. The Rams will stiffen up this week as they lost a close one last week and also have been dragged through the mud a bit thanks to a late hit to Teddy Bridgewater. Langford was impressive but I doubt he is matchup proof. Regardless of the bad matchup if you have him he is worth a flex start.
St. Louis Rams
Todd Gurley (Running Back): Chicago allows the 14th fewest fantasy points to running backs, but then again they never played Todd Gurley. The Bears have yet to stop a completely run heavy team because they really have not faced one yet. In week 9 Danny Woodhead put up some solid fantasy numbers against them so it is completely possible Gurley could have some heavy production catching balls out of the backfield. Gurley is a RB1 every week.
Tavon Austin (Wide Receiver): Austin struggled last week against Minnesota's stiff defense however Chicago is a little more malleable. The Bears have given up the 14th most points to wide receivers, that coupled with the fact that Austin also runs the ball in different formations could yield him some solid production. Austin is a solid flex play this week.
