On the ESPN postgame, Trent Dilfer had a good take on it. He basically said that Atlanta's success this year as an offense was based a lot on the big-play attack, and that "it'll make you smile but it'll make you cry". The Falcons always had big leads this year. They never really had to play a close game. And, in this game, once again they sprinted out to a big lead (not due to their offense, but due to Patriots' turnovers). So when the game tightened up, the Falcons--or, at least, their coaches--just didn't know how to play a different game. Of course everyone in the world who ISN'T on the Falcons coaching staff thinks they should've run-run-FG. But even Kyle Shanahan said afterwards, "Well, we tried to run on 2nd-and-1 and got stuffed, so..." This is why Belichick is the GOAT: almost every time, with rare screwups by him, he'll do what needs to be done to win the game.
