To protect the integrity of the league they are not gonna lay down at home to a division rival.....If the Niners lose before the Seattke game, they will sit theurcstarters because they've illegally ve locked into the 6th seed, unless they lose both games, thrn the 7th seed. In either case, not worth playing starters without any significant change in seeding.
So Seattle and Niners need to both lose before week 18. If only one loses, that team will rest their starters, unless we drop a game and then it doesnt matter for us anyway.
