Who Should I Start? Christian McCaffrey or Marlon Mack

Friday, September 18, 8:59 PM

San Francisco 49ers running back Christian McCaffrey had 68 rushing yards on 10 carries and converted eight targets into five catches for 20 receiving yards in last week's win over the Rams. His modest output in that game resulted from the 49ers' overall dominance and the effectiveness of backup Kaelon Black (groin), who had 14 carries of his own. With San Francisco heavily favored against the Dolphins in Week 2, there will be less of a need for McCaffrey to produce. However, Black was nursing groin tightness in practices this week and is listed as questionable for Sunday. Restrictions on Black may increase McCaffrey's workload, or open the door for backup Jordan James to get involved. Regardless, McCaffrey's status in San Francisco's offense and his effectiveness when on the field keep him in contention for a top-five finish. As in any week when McCaffrey is healthy, he is a must-start.
