Trade help: Dion Lewis and Keelan Cool for my Gio Bernard and Njoku?

12 team full ppr league

My RB’s are DJ, Devonta Freeman, Jordan Howard, Kerryon, and Gio right now.

My WR’s are Marvin Jones, Corey Davis, Demaryius Thomas, Sterling Shepard, and Ryan Grant.

I have OJ Howard and Njoku as my TE.

I’m really conflicted about this offer. On one hand Dion provides much better long term value than Gio (although the Titans offense hasn’t looked very good) and I don’t need Njoku with OJ Howard on my roster. But on the other hand, Gio seems to be a really good play this week and I’m not sure this trade necessarily improves the starting quality of my lineup going forward
