Roster is basically built on Trent Williams, Christian McCaffrey, Nick Bosa... McCaffrey already turned 30.

STACKED’s take

Negative signalInjury

McCaffrey's age (30) is part of 49ers' aging core fragility concern.

Christian McCaffrey is a foundational piece of the 49ers' roster, but at age 30 he represents aging core talent; the source notes McCaffrey 'already turned 30' as part of the broader concern about the 49ers' aging, injury-prone roster construction.
