defense is a struggle for everyone at some point. hell playing against 3 * teams i still give up 30 points sometimes. i would recommend controlling a interior d lineman or a defensive end. this allows you to have control in stopping the run. once you shut down the run game, it makes the opponent one dimensional. stopping the pass is often difficult. ive had my best success by just using a mix of zone blitzes, cover 2, and man coverage. controlling a defensive lineman will also allow you to get some pressure on the quarterback to force some incompletions. let me know if this helps!
