RB Raheem Mostert
It’s hard to imagine Mostert taking another step forward after his stellar second half of 2019 and dominant NFC championship game performance. However, there’s plenty of room for Mostert’s role to grow. A crowded backfield will keep any back from ever garnering true No. 1 running back carries in San Francisco, but Mostert should see more than the 137 totes he got last year. There was an eight-week stretch in the middle of last season where he had just 39 attempts. Mostert averaged 13 carries per game over the final five contests. That’s probably closer to where he’ll be through all of 2020, and he could see his production skyrocket because of it.
