Need Running Back Help

Im in a full ppr league. Im growing weary of Fournette, especially playing the Seahawks. Should I sit him? And if so then who should I sub in??? Thanks.

Options:
Christian McCaffrey vs Minnesota
Rex Burkhead vs Miami
Afred Morris vs Washington

I’d probably stick with Fournette, as difficult as that might be. If you choose not to play him, I’d lean toward Burkhead out of those three.
