I am no fan of the way the team conducts business on offense, but if the Defense can pressure Brady, it could come down to the 4th quarter on a low scoring game.
Of course, a blowout by the Patriots wouldn't surprise me either, but for the most part, every game with the Rams is a game of punts and close and if the other team plays poorly and makes mistakes the Rams can back into a win, provided the defense and special teams both make big plays.
The problem with the Rams is that the team is incapable of winning if the other team plays well because the offense is just so bad.
