Sit / Start for FINALS (1/2 pt PPR league)

I am having a very difficult time deciding on who to play and flex between these 5 guys (I just lost Antonio Brown before my finals match-up and trying to recover) I have:

Sterling Shepard
Cooper Kupp
Martvius Bryant
Marquise Goodwin
Jonathan Stewart

I am starting Kareem Hunt and Jerick Mckinnon at my RBs, because I still think that is a good idea.

My questions is who between those guys should I start for my receivers and my flex?

All input appreciated!
