You can go back and look at several games in the last few years where the defense held some good teams to low scores, but the offense totally disappeared. After hearing about how the offense was going to be unstoppable with the best WRs and RB , they failed to recognize that the QB was incapable of using the weapons that was at his disposal. There is no need to draft another WR early in the draft. The QB can’t find the ones that are already on the team. They don’t need another WR that gets open, but is rarely thrown to.
