Who do I target to upgrade my team?

If I finish strong I can get into the playoffs. But it’s gonna be hard with my current team. (PPR league)
QB Prescott, McCown.
RB Hyde, Javorius Allen, Theo Riddick, Andre Ellington, Matt Breida, Marshawn Lynch.
WR Devante Adams, Paul Richardson, Sammy Watkins, Travis Benjamin
TE Zach Ertz and I streamed Vernon Davis this past week.

I’m in need of an upgrade at WR because I can’t rely on those guys to produce every week. But who do I give up and what type of player do I target?

Robert woods if he’s on waivers or try to trade, could go for Crabtree, very consistant . I’d say theilen but just a monster week and might be too much. Brandin Cooks has been consistant as well. Sterling Shepard could be another good target. Corey Davis could start seeing more and more targets as well

Thanks for the advice, now I need to figure out who to give up :S

you can drop your McCown, pretty sure you can ride Dak ROS, drop a Davis because Ertz will be back and you can drop Ellington to make more room. Ellington not enough targets / production to be on a roster right now.
