Like with Chase Edmonds, this was the expected move on a short week. Coach Kliff Kingsbury has already proclaimed the running back group will operate as a committee, headed by Kenyan Drake and Alfred Morris. It's a very difficult matchup for the Cardinals backs, as San Francisco ranks No. 2 in our schedule-adjusted rankings for points allowed to running backs. Between the 49ers stingy defense (allowing under 100 rushing yards per game), the timeshare between the running backs and the short week, this is not a situation to put a ton of faith in for Week 9.
