NEED HELP! Trade Josh Jacobs for Marlon Mack?

Half ppr league. Also full point for first downs.

I could use a boost to my rbs, but Mack is injury prone and not really used in the passing game.

I’m set at wr and te.

Here are my rbs…Carson,Penny,Breida,Pollard,Gallman.

I also have Engram and Waller. I’m not sure about having both Jacobs and Waller in my lineup though.

Any advice? Please help, thanks!
