Easiest with two controllers. Simply use a pass play on offense with your main account in which your tight end runs a deep route. Choose Field Goal Block on defense with the second controller. As soon as the ball is snapped lob it to your Tight End and run it in for the touchdown. Rinse and repeat until you score 3 touchdowns by either trying to recover an onside kick or by punting the ball back to your main team. The achievement will unlock once the game is over.
