This movie doesn't aim to run up the score; instead it plays an entertaining game of American football by keeping the score close for drama and by utilizing a variety of wild plays with interceptions, fumbles, etc. Thus, the movie manipulates luck often.
Arc: [I] chose Colts vs. Patriots because in recent years the two teams have played many intense, high-stakes games in which the Pats always escape with a victory[1]. :-(
