Apparently John Stokes has read the football textbook chapter "How to stop an opponent from diving into the endzone from the one yard line."
Step 1: Carefully flow to the area where the ball carrier intends to cross the goal-line after he propels himself into the air.
Step 2: Plant both feet firmly just behind said area along the goal-line. Lean body slightly forward so head, arms and chest are slightly in front of the vertical scoring plane of the endzone.
Step 3: Receive full weight of ball-carrier's body in midair, preferably with your face and hands. Halt forward momentum of ball-carrier. For best results, use lower body strength to begin to reverse the momentum of the player before continuing on to step 4.
Step 4: Use upper body strength to guide opponent's body successfully into the turf short of the endzone.
For added dramatic effect, wait until 3rd and Goal before successfully executing the manœuvre.
