Time for a must win

I’m In what’s projected to be a close weekend and need the win. Our league is big and doesn’t leave much on the wire to pick over. Currently I have Flacco subbing for Rivers(following Mike’s strategy). I picked up Jalen Richard thinking the pass catching back might see a bump with Cooper leaving. Would it be worth getting Carr off the wire for a stack as he and Flacco have similar projections this week? Or am I chasing points that aren’t there?
