Need some trade advice please!

Full PPR looking at either Bell or Henry. Nervous about Ekeler with Gordon back luckily I have kamara… my other RB2 are Sony and Coleman so ya you get it. What do you think would be a decent offer to get 1 of these guys? Or should I maybe wait and hope that Ekeler has a good game and sell him after that? Thanks!
