Since the Bills are the only undefeated team in the AFC and one of three undefeated teams in the entire league (seriously, who would have thought that the Bills and Lions would be undefeated at this point?) they are likely going to be pretty heavy favorites in Sundays game against the Bengals in Cincinnati. The Bills average the third most yards per game in the NFL at 431 yards behind the Saints (437.7 yards per game) and the New England Patriots (540.3 yards per game).
They will go head to head with the Bengals defense, who have allowed an average of 276.3 yards per game, which places them as the third-ranked defense behind the Pittsburgh Steelers (263.3 yards per game allowed) and the Tennessee Titans (261 yards per game allowed).
The Bills have the 11th ranked passing offense in the league. Quarterback Ryan Fitzpatrick has an average of 37.3 pass attempts per game for an average of 276 passing yards per game. He has thrown nine touchdowns to four interceptions and has a passer rating of 98.8.
The Bengals have the fifth ranked passing defense. Teams have attempted passes on the Bengals defense an average of 31.7 times per game for an average of 188.3 yards per game. There have been four touchdown passes thrown against the Bengals and the Bengals have intercepted one pass.
The Bills have the fourth ranked rushing offense in the NFL. Fred Jackson and to a lesser extent C.J. Spiller have carried the ball an average of 27.7 times per game for an average of 155 yards per game. The Bills have scored four touchdowns on the ground, they have six carries over 20 yards (2nd), one carry over 40 yards (4th) and they have fumbled the ball one time.
The Bengals have the seventh ranked rushing defense. Opposing running backs have attempted to run the ball an average of 30.3 times per game against them for an average of 88 yards per game. The Bengals have allowed only two touchdowns on the year and they have allowed zero runs of over 20 yards (1st), the longest carry against them being 17 yards. They have also forced two fumbles.
Inversely, the Bills have the No. 26 ranked defense in the league, allowing an average of 387.3 yards per game (271.7 in the air and 115.7 on the ground) and the Bengals have the No. 25 ranked offense averaging 301.3 yards per game (204.7 in the air and 96.7 on the ground).
Considering how tough the Bengals' defense has been and how bad the Bills' defense has been, maybe the game won't be as big of a blowout as many are likely predicting it will be.
