Can someone explain to me how the Spartans in the stands saw on the replay monitors that Riley hit the player below the shoulder with his forearm across his chest? That's why the fans were booooooohing at the refs. Yet when I got home and watched the copy of the game, the hit was definitely helmet to helmet? It was a slightly different angle but the level of his head was NOT the same. HOW can that possibly be? Can you explain how many different camera angles there are? How many people are deciding WHICH angle is shown?
