They say football is a collision sport, and the Georgia defense is giving opposing ball carriers a taste of massive impacts. All year the defenders have made teams pay for the privilege of gaining yards – and pay dearly. The hits have been teeth-rattling, spirit crushers. From close range, the impacts often making me wince empathetically. Opposing players are not going to want to take on the Dawgs again anytime soon after getting beat up on a Saturday night in Athens.
