Mike Preston, columnist: Just about everyone thought the Ravens had improved this season, especially in the passing game, but we didn't know how much. We still don't know because the Buffalo Bills were terrible Sunday. Regardless, the Ravens did exactly what they needed to do. They beat up on a bad team and they did it convincingly. Quarterback Joe Flacco threw the ball well but more importantly he was mobile. He got all of his receivers involved in the game and took advantage of the Bills in the middle of the field. Defensively, the Ravens simply dominated Buffalo. They took running back LeSean McCoy out of the game early and forced quarterback Nathan Peterman to beat them. Overall, a great start for the Ravens. It could not have gone any better.
