Big difference: Andy Dalton has been sacked 28 times this season (2nd-most in NFL). Last year, Dalton was sacked 20 times all season.
Down year for Bernard: RB Giovanni Bernard is averaging 35.1 rush yards per game and 3.8 yards per carry this season (both career lows).
Potential milestone up for grabs: If A.J. Green gains 36 receiving yards against Buffalo, he will reach 1,000 for the sixth straight year. Only one other WR (Randy Moss) has started his career with six straight 1,000-yard seasons.
Iffy defense: The Bengals have allowed 27+ points in four of nine games this season. They allowed 27+ points in two of 16 games last year.
