3) 18th in the passing game (202.9 ypg)

By strengthening our defense, we'll be able to give the ball to the offense more, which will increase the time of possesion, passing yards, rushing yards, scoring, & total offense. Basically, it increases the opportunities we have to score & reduces the opportunities the enemy has to score.
You could argue that a strong offense is a good defense by keeping the other team off the field, but everyone knows that defense wins games & ultimately, Championships.
