Is Rashaad Penny worth owning?

One upon a time I owned Reggie Bonnafon, Rashaad Penny, and Alexander Mattison.

I still own CMac, Dalvin Cook, and Chris Carson. But have since dropped Bonnafon as Carolina signed Mike Davis and there’s no clear handcuff.

Should I keep Penny given Carson is my 3rd back anyways and has looked awful with whatever limited work he has received?

The bad news is I have Amari Cooper, Emmanuel Sanders, and Darren Waller. The good news is I will make the playoffs. Would you use this space to bolster depth at WR/D/or kicker.

Any thoughts?
