SANTA CLARA - One of the bright spots in the 49ers loss to the Green Bay Packers was the performance of running back Raheem Mostert.
Mostert had a tough go the week before when he fumbled the ball on his first carry facing the Arizona Cardinals. Coach Kyle Shanahan challenged the running back after the mishap and Mostert said he took it to heart.
“I need you to step up,” Mostert said Shanahan told him. “I need you to focus more on ball control. I know you don’t get many reps in practice but when you do, you have to make them count.
