I think the offense will show up. They'll stick to 11 personnel and continue to spread the ball to different receivers while making a conscious effort to run the ball.
Unfortunately I don't think the defense can keep the Bengals or any other top caliber team from scoring often.
I don't expect Beane to make any trades to shore up our shortcomings on D (SURPRISE!) And it's just gonna be too hard to keep good teams from scoring with what we have currently.
They couldn't put away the Giants, NE or Bucs from winning or keeping it close in the 4th. Whether it be players or coaching decisions. 3 of the worse offenses in the league that had no business in the game.
But, I will continue to hold out hope, GO BILLS!!!
