Trade advice 0.5 ppr

I was offered Fournette, Powell, and a next year 2nd round pick for Kamara.

I can keep Powell for a 10th next year, but Fournette and Kamara go back to the draft pool. What would you do?

Current backs are: Kamara, K. Johnson, R. Jones. Had 2 other backs go down with injuries (McKinnon and Burkhead).
