Trade talks for gronk

My RBs are dj, Howard, Gordon, drake, Sony, kerryon. I have Njoku at TE. Should I trade David Johnson for Gronk? Or should I wait and see what baker does for njoku.

I’d rather go get Ertz or even Graham and pay less than what you’d have to give up for Gronk. DJ is too much imo. I think he’ll pick it up.
