Green Bay is definitely the safe play. Detriot cant put up big numbers on their best days. However, GB's D isn't likely to score a lot of fantasy points, they just wont lose a lot.

KC has a D that can make big plays and lead to more fantasy scoring. Dallas plays well at home but they dont score much either.

I think your opponent has a lot of tough matchups, edge and harrison on the road against a very good jax D, and brees and gates at home against a solid Miami D.

Overall, I think you have an advantage so I'd go with the safe play and start da Pack's D.
