Brandon Aiyuk, eight months since tearing multiple knee ligaments, is making a remarkable recovery, 49ers general manager John Lynch says.

It’s no accident the 49ers had trouble in the red zone last season with McCaffrey unable to dent the end zone. Any hope they have of reclaiming the NFC West and becoming a factor in the postseason rests with a return of the McCaffrey of old and not an “old” McCaffrey.
