Pick 2 for 0.5 PPR playoffs

RB Jonathan Williams
RB Chris Carson
WR Michael Gallup

0.5 pt PPR
Week 1 of Playoffs (1st round is weeks 13 & 14 combined)

I have McCaffrey, Evans and Chark starting, so I’m trying to determine my RB 2 and flex.

Any help would be appreciated. I am paranoid about Carson vs. Min. Thinking about tilting to Gallup.

Williams and Gallup
