Who do I dump edition (for playoffs)

Alright, below are my candidates to drop if I need to make WW moves tonight. Am already in the playoffs which start on week 15.....so have a week to get ready for the playoffs

current starting RBs: Kamara, Gordon, Drake
current starting WRs: Fitz, Thielen, Hilton

dump candidates:
Emmanuel Sanders
Chris Hogan (back at practice today so hold mode)
Davante Booker
Austin Eckeler (insurance on Gordon)

Am weak at TE (Vernon Davis) and DST (Skins) so wanna shore up those positions but who do I dump besides Davis and Skins.....wanna garner some depth at RB and WR too if possible

Thanks
