Dee Ford and Nick Bosa were great roster additions, but the secret to this 49ers team’s dominance is the players that only die-hard fans have heard off — the Raheem Mostert’s and Emmanuel Moseleys and Sheldon Days.
This team is suddenly very deep and talented, as a bunch of unheralded free agents and late-round picks have turned into solid rotation players, capable of starting if the injury requires. Consider:
A walk-on tight end at San Diego State. UDFA. Two years on the Atlanta Falcon’s practice squad without making their 53-man roster.
