re: 49ers Backfield ROS outlook

Mitchell is the guy when healthy. The Shanahan offense prefers a speed guy. Mitchell has top end speed that the rest don’t have (like Mostert and Matt Breida both had - they were primary ball carriers for at least one season). Shanahan makes his system so RB just has to read the holes, follow their blocks, and explode through the 2nd level for big gains. Notice the WRs that can block downfield always get play time. Ball carrier vision and speed, nothing else. Shanahan doesn’t care if his RBs can break tackles or anything else - they’re always low in broken tackles and yards after contact, but high in yards before contact
