Trading Kupp + ___ For Bell?

So, I have a glaring need for a stud RB. I have good receiver depth (M. Thomas, Kupp, CDavis, Gordon, Lockett). I am currently 2-2, and am concerned with my ability to win later in the season without a stud RB.

At the same time, I would be lacking at RB & WR for a few weeks if I were to trade for Bell.

What would you guys do in my situation?
