The Giants matched the Saints blow for blow. But in the end, one play determined the outcome of the game.
We can talk about the utter lack of defense on behalf of the New York Giants, though they did manage to come away with a pair of interceptions*.
*The second interception was ultimately ruled a fumble returned for a touchdown. While this is good for Drew Brees' stat line, its a semantic that doesn't effect the game.
Or we could talk about the incredible night by the Giants offense, particularly by Odell Beckham and Eli Manning.
