Rapid Reaction: Buffalo Bills

ORCHARD PARK, N.Y. -- A few thoughts on the Buffalo Bills' 19-0 win over the Miami Dolphins:

What it means: Quite the showing by the Bills' defense, which recorded its first shutout of the season. Only three Dolphins drives crossed midfield and Miami never entered the red zone. The Bills improve to 3-2 in the division and 4-3 at Ralph Wilson Stadium this season, which are small milestones for a team that had already been eliminated from the playoffs. They've also won back-to-back games for the first time under coach Doug Marrone.

Sack attack: The Bills came into the game as the NFL's leaders in sacks. The Dolphins entered Sunday allowing the most sacks. It hardly came as a surprise, then, that the Bills notched seven sacks in their shutout win Sunday. They now have 56 on the season, which shatters their previous franchise records of 49 (in 1995) and 50 (in 1964, before sacks were an official statistic).

Woods ejected: Receiver Robert Woods was ejected in the third quarter after throwing a punch at Dolphins safety Reshad Jones. The two players tussled after a play and took it to the ground, with Woods taking a swing at Jones' helmet. Woods argued with an official before being escorted off the field.

Goodwin injured: The Bills' other rookie receiver, Marquise Goodwin, left in the first quarter with a knee injury. It was quickly announced that he would not return, which may not be a good sign for the third-round pick from Texas.

Stock watch: Fred Jackson, rising. Jackson will turn 33 in February but shows no signs of slowing down. He rushed 19 times for 111 yards on Sunday, his first 100-yard rushing game of the season. That's an impressive performance in Week 16 for any running back. Jackson also surpassed 5,000 career rushing yards in Sunday's win.

What's next: The Bills, now 6-9, wrap up their season next Sunday in New England. They remain in fourth place in the AFC East.
