Bolster team for Playoffs

Hey FootClan, I have clinched a playoff spot (9-3) and am looking to bolster my team. There are some solid players left over from waivers and was seeing which ones would be worth picking up, and who I should drop to acquire. 0.5 PPR. Any other advice is greatly appreciated!

Available Players:
RB: Martin, Montgomery, Gore, Burkhead, Woodhead (was DROPPED during waiver claim)
WR: Hogan, Kupp, Doctson, Amendola, Kearse

My Team
QB: Kirk Dak

RB: Bell Mixon McKinnon

WR: Crowder Baldwin D Thomas JuJu Shepard

TE: Gronk Engram

D/ST: Ravens (LOVE their week 15 & 16 matchups) Chargers

Assuming chargers are a one week rental, and you already clinched a high enough spot, I would drop them for hogan. He could come in very handy as a flex or wr2 for playoffs. I’m not sure if any of those rbs interest me.

Chargers are for this week and next (Cleveland then a Washington). Ravens have lions and @ Pitt those weeks. I’m wondering Shepard with his migraines and now with Geno smith. Am I good enough with these 3 RBs? Woodhead would be my first choice of those RBs and Kupp is intriguing to me
