Fighting to stay alive

8 Team PPR, in the 2nd week of Round 1 playoffs. With Kamara down and a few other low-scorers I’m down 87-123 and need to win this week to keep on. Need advice for who gives me the best chance to win this week. Here’s my current lineup:

Starting:
Case Keenum vs Bengals
Alvin Kamara vs Jets, Kenyan Drake vs Bills, LeSean McCoy vs Dolphins
AJ Green vs Vikings, Josh Gordon vs Ravens
Evan Engram vs Eagles
Jaguars DST vs Texans
Jake Elliot vs Giants

Bench:
Tyreek Hill vs Chargers
Jordan Howard vs Lions
Mike Evans vs Falcons
Ravens DST vs Browns
Mark Ingram vs Jets
Robby Anderson vs Saints
Philip Rivers vs Chiefs

Opponent has: Kirk Cousins, Devonta Freeman, Kareem Hunt, Michael Thomas, Michael Crabtree, Travis Kelce, Keenan Allen, Texans DST, and Justin Tucker

Nervous about my WR options in tough matchups. Not sure which RB options are BEST this week. Stack my team with same team options (Rivers with Allen, Hill with Hunt/Kelce, Kamara/Ingram with Thomas) or spread it out? Also open to picking up waiver options!

Thanks Footclan!
