Trying to acquire David Johnson

2 QB, 10 team dynasty, we cut to ten players at the end of every season.
0.5 PPR RB, 1 PPR WR TE

Cousins, Ben, Winston FItz
Cook, Mixon, Royce Freeman, Duke Johnson, Corey Clement, Latavius Murray
AB, Evans, Alshon, Fuller, Mike Williams, Pettis
Gronk, OJ Howard

Guy with DJ is on tilt. Do I offer him Cook, Latavius Murray and Royce Freeman for DJ and Gio Bernard?
