Dalvin cook security trade

Should I trade for Mattison beimg i own dalvin cook. I would give up Devin Singletary. My backs are Cook, Michelle, Montgomery, Singletary and Morsett

Yes you should have Mattison with cooks injury history.

I have him on many teams and I don’t own cook anywhere. Regretting those decisions.

Who is the last back you have? If it’s mostert from SF, I’d probably drop him for Mattison.
