Amari + Fant for Kelce OR Amari + AJ Green for Ekeler

12 Team .5 PPR.

My Team
RB: Kamara, Mixon, Gibson, Akers, and L Murray
WR: Amari, A-Rob, Chark, AJ Brown, AJ Green and B Cooks
TE: Fant

Thoughts on if either of these are good deals and which one would you personally prefer in my situation?

Bonus question: Pick one to keep and one to trade. A-Rob or Amari?
