Your team has been consistently beaten in the air and up the middle the entire first half. The defense against the rush has been solid as well as against passes to the sidelines, giving up minimal yardage, but the other team was repeatedly going to the air in the middle of the field during the latter part of the first half and finding all your holes. Adjustments are part of coaching — discuss defensive adjustments that you, as the coach, might make at half-time to combat this situation. Defend why you feel you would make these adjustments.
