10 team PPR

DeVonta Smith vs KC

DJ Moore vs Det

Brian Robinson vs NYG

In a 10-team PPR, I have RB: CMC, DSwift, BRob, Mostert. I have WR: Keenan, Davante Adams, Devonte Smith, and DJM.
We start 2 RB, 2 WR, 2 Flex.
I’m obviously starting CMC, and Keenan (if healthy) + Davante Adams.
Who would you start in the 2nd RB, and who would you flex?

Full PPR Keaton or Brian Robinson?
