Raheem Mostert, the 49ers’ original track-star RB, says patience is key for Isaac Guerendo (paywall)
“Asked about Guerendo and the challenges of learning the 49ers’ system — and satisfying Turner — Mostert noted it took at least two seasons until he was truly comfortable running the outside zone. And he knows exactly what Turner is preaching to Guerendo in the running backs room.
Though the 49ers coveted his speed, they didn’t want Mostert at full gallop all the time. Turner wanted him to regulate it. The goal is to find a balance between putting stress on defenders and allowing tight end George Kittle and the offensive linemen to get in position to create a run lane.
