All my options fell off

So I’m in a full point PPR keeper league. My keepers are D. Johnson and Ertz. I was planning on making some moves this offseason, but I play with some scrubs who just like to throw guys on the block for shits and giggles but then keep them. Iv been asking a lot of trade questions as of late so I appreciate the patience. Anyways…does anyone think I should make a move on McCaffrey, McCoy, McKinnon, Howard or Cohen?? If so so what pick should I offer?? I really really want to nab an RB that I can pair with DJ. Or do you guys think I should stay with DJ and Ertz?? Really appreciate the help.
