Between the two Championship games and the Super Bowl there is a week off that no football games are being played. They have a week to move everything back. They do not have to play any football games this weekend. Also, there is no Monday Night football game next Monday, so they can play this game next Monday. If they do not want to play any games this weekend they can skip it and play week 18 the following week instead. By playing no football games this weekend, they can play the following week and push all the playoff games back one week, and as a result they will not have a week off between the two Championship games and the Super Bowl.
