Seattle elevates Bohanna and Griffin for Week 1 vs SF, pledging veteran depth to a young roster. Bohanna adds interior bulk to slow SF’s ground game, while Griffin provides immediate secondary help. The move signals Seattle prioritizing run defense and versatile coverage as the 49ers challenge the new-look defense.

Fantasy takeaways hinge on Bohanna’s potential snap-up in a run-stuffing role and Griffin’s early involvement in man coverage, which could boost tackles and opportunistic plays for Seattle’s corners and linebackers in a Week 1 showcase against a potent SF offense.
