The matchup looks enticing for Mostert, but the competition at his position makes him less appealing of a start this week. Tevin Coleman and Jerick McKinnon both figure to be key parts of the game plan for the 49ers, which is going to cap Mostert's ceiling. He'll receive around his 12-15 touches, but very little involvement through the receiving game pushes his value down a bit. He's going to have to score for you to feel happy starting him this week. Mostert is a borderline RB3/FLEX option for your lineups against Arizona.
