Waiver priority advice plz

I have the first waiver priority in a standard league im 5-0. I have the seahawks D with a bye week and the jags are on the waivers. There is also some other good players on waivers like brate (i have rudolph) fuller, thompson. Do i add brate with my first priority or jax D or i keep my priority? I would drop martavis for jacksonville. My team is : hunt gurley hilton julio martin dak (bye) kirk amari martavis kamara
