RB2 Help 1/2 PPR

Hey guys. Need some help with my line up. 1/2 ppr.

QB: Philip Rivers
RB: M. Gordon, Jamaal Williams
WR: OBJ, Adam Thielen
Flex: Amari Cooper
D: Chargers
K: Jake Elliot
Bench: Rex Burkhead, Emmanuel Sanders (wishing I started him), Keelan Cole, Matt Breida, Jordan Wilkins, Latavius Murray, Marcus Mariota.

I think I need help on my RB2 position. I have first pick on the waiver wire. Is it worth using my first pick for any of these:
A. Ekeler
P. Lindsay
T. Yeldon

Or should I hold out for a more talented player to emerge?

My second option is to attempt to offer a trade for K. Hunt. The owner has:
Cam Newton, K. Hunt, J.Ajayi, J.Jones, D.Funchess, Z.Ertz, Geo Bernard, Josh Gordon, W. Fuller, Nelson Agholor, S.Michel, Pat Mahomes, Chris Godwin, Tyrod Taylor.

Not sure I have anything to offer him here though.

My third option is to do nothing. Stick to Jamaal Williams and Rex Burkhead.

Appreciate the help.
