Trade Rob Kelley for Crowell would you do it? STD League

My Rbs are: DeVonta Freeman, Jordan Howard, Marlon Mack and Kelley
My Wrs are: Mike Evans, Amari Cooper and Sterling Shepard

I would do that. Even though Crowell has been inconsistent Rob Kelly has been injured all year and Thompson seems to be getting the bulk of the running back work. The both in slumps right now but I see Crowell having the better upside1
