Amari Cooper for Isaiah Crowell trade?

I just got a trade offer for amari cooper for isaiah crowell. i am a ajyai owner but since he is on the IR now for the season. I’m lacking in RBs. I have Karmara and buck allen and I got alfred morris and ronald jones off of waivers today.

My wrs are baldwin, john brown, clavin ridley, lockett and taylor gabriel, and amari cooper

in a 12 team league half ppr I’m at 4-1 currently

Should i take the trade?
