Dalvin Cook on the waiver wire

okay guys so someone in my league dropped Dalvin Cook. I want to pick him up, but I’m not sure it will be worth it right now especially since I already have Fournette sitting on my bench. I was thinking about dropping Jalen Richard for Cook. what are Y’alls thoughts?

my current roster
QB - Matt Ryan, Big Ben
RB - James Conner, Nick Chubb, Joe Mixon, Fournette, Jordan Howard, Jalen Richard
WR - John Brown, Chris Godwin, Cooper Kupp Odell Beckham and Courtland Sutton
TE - E Engram

I would drop Jalen Richard immediately and get Cook. If Cook comes back, you’ll have him during playoff crunch time/playoffs.
