Ditch Fatty Fournette?

A couple months after our start up draft I’m thinking about trading Fournette and a pick for Etienne. Since our whole league is new to dynasty I’m not sure how to value picks. Is Fournette and a 2nd for Etienne too much? Should I just hold Fournette?

My RBs are:
Akers
Fournette
Spiller
Rachaad White
Davis-Price
Michel
Henderson
Jeff Wilson

That’s a good offer. I would put it out there
