The San Francisco 49ers running backs struggled in a big way in the second half against the Buffalo Bills. Carlos Hyde rushed for 37 yards in the first half (4.1 ypc), and then 15 yards in the second half (3.0 ypc). Hyde suffered a shoulder injury, and while he did return for some stretches of the second half, we saw more work from the backup running backs. Normal No. 2 Shaun Draughn rushed for two yards on one carry, while normal No. 3 Mike Davis had 13 yards on five carries.
On Monday, Chip Kelly was asked what changed with the use of Davis over Draughn.
