NFL Nation: Sebastian Janikwoski

OAKLAND -- A look at a critical AFC West game.

What does it mean: The AFC West is now a muddled mess. The Chiefs, who have been leading the division all season, are now 5-3. The Raiders are 5-4. The San Diego Chargers, who have won two straight games, are 4-5. The Raiders, who won the game on a 33-yard field goal by Sebastian Janikowski, haven’t won more than five games in a season since 2002. Oakland is 3-0 against AFC West competition this season.

Tomorrow’s talker: The Raiders are one of the hottest teams in the NFL. They’ve won three straight games. They didn’t cruise against the Chiefs as they did in their previous two games, but they made the plays they had to make.

Sloppy times: This game was messy. The two teams combined for 27 penalties (the most in the NFL this season) for 240 yards. The Chiefs lost 10 points on penalties.

What’s next: Oakland has a bye and Kansas City plays at Denver on Sunday.

ORCHARD PARK, N.Y. -- If the Buffalo Bills want to establish themselves as the best team in the AFC East, they need to wake up in the second half against the Oakland Raiders.

The Miami Dolphins are working on what would be a shocker of a victory over the New England Patriots in Foxborough, Mass. The Dolphins are ahead, 21-6, at halftime.

My earlier post about the Dolphins slipping below .500 in the post-Shula era looks like a royal jinx.

The Bills are making enough mistakes to be trailing an inferior team 9-7 at halftime. Marshawn Lynch was able to skirt the defense, tiptoe along the left sideline and score a 14-yard touchdown to put them ahead, 7-6.

But the Bills have fumbled three times, including their last two first-half drives. Quarterback Trent Edwards fumbled on the Bills' 40-yard line to set up the go-ahead 32-yard Sebastian Janikowski field goal. Wide receiver Lee Evans coughed it up on the Raiders' 28-yard line with 40 seconds left.
