49ers backfield depth drives early fantasy talk this season. Brian Robinson Jr. lands as the clear RB2 behind Christian McCaffrey, delivering a high-ceiling handcuff if McCaffrey misses time. Guerendo’s outlook softens with Robinson in town, leaving him with limited workload unless injuries strike. In drafts, Robinson looks like the smarter target with an ADP around RB30; Guerendo sits about RB47 as a deeper-league flier.

Robinson’s profile as a between-the-tackles grinder with receiving ability fits Shanahan’s system, giving him standalone value in limited scenarios and top-tier upside if CMC is out. Guerendo’s path hinges on chaos at the top of the depth chart; in most leagues, he’s a wait-and-see stash unless injuries create a sudden opening.
