First, you play keep away. You grind out first downs and kill the clock. Second, you rush the hell out of him. Third, and this is the most important one, you score TDS when you get into the red zone and build up an insurmountable lead. Fourth, you absolutely punish his receiver and allow no RAC yards. Fifth, in the case of Brady, you take whatever countermeasures to protect your team from his cheating. Sixth, you need to change the looks on D so he can't just read it presnap. Seventh, your O can't turn the ball over.
