Who to keep - Chark vs Mostert - 1/2PPR

Chark or Mostert for a 9.10 pick in 1/2PPR Keeper?

I’d say Chark, but I’m drafting 10th and I think all the RB value in the late first will be gone (No Drake, Jacobs, Sanders, Ekeler) and the likely best available will be Mixon/Hopkins/Chubb. I’m keeping Jones at 2.03 and Godwin at 3.10.

Chark. Go for the best player.
