Bears change backfield in preseason finale

We saw different usage in the Bears backfield in Saturday's preseason finale vs. the Bills. RB Khalil Herbert played the first- and second-down snaps on the first two drives. But he was replaced by RB Roschon Johnson for 3rd-and-10 and 3rd-and-11 snaps. RB D'Onta Foreman played the third drive. Herbert remains the top fantasy option in this backfield, but it doesn't look like his role will be as valuable as we thought after the preseason opener, when he played all seven of QB Justin Fields' snaps.
