The Buffalo Bills dominated the San Francisco 49ers Football on Sunday eveningsrumbled past them 35-10. Not only did this win help them keep pace with the Kansas City Chiefs for the top spot in the AFC, but it also helped the team win the AFC East for the fifth consecutive year. Here are four takeaways from Sunday’s big win:

Even on a night where No. 17 only threw 17 passes, Josh Allen continued to prove why he should be the favorite for the league’s Most Valuable Player. While his passing stats may seem dull in the box, completing just 13 passes for 148 yards on 17 attempts, the Bills’ superstar signal-caller made plays when it mattered most. Allen has shown that he can do anything; He passed for two touchdowns, rushed for another and scored a receiving touchdown thanks to a quick-thinking lateral from wide receiver Amari Cooper. Buffalo’s field general continues to shine in the biggest moments and, thanks in part to his performance tonight, is the clear favorite to win this season’s MVP award.

One of Buffalo’s strengths this season has clearly been its much improved running game. The consistent use of a sixth offensive lineman and the contributions of the entire running back room have taken a huge load off Allen’s shoulders – and legs – this year. In a game where the elements played a big role, the Bills’ running game didn’t disappoint. James Cook continues to cook; The third-year senior carried the ball 14 times for 107 yards and a touchdown, averaging a whopping 7.6 yards per carry. Rookie running back Ray Davis added another 63 yards and a touchdown on 11 carries, while change-of-pace back Ty Johnson also joined in on the fun, adding another five carries for 28 yards. As the weather gets colder and the elements continue to play a role, it will be very important for Buffalo to rely on its running game to peak at the right time.

Buffalo’s victory over the 49ers gave the Bills their fifth straight AFC title and their sixth straight playoff appearance. Buffalo is now the second team this season after the Kansas City Chiefs to secure a spot in the playoffs. However, they are the first team this season to win their division, guaranteeing there will be at least one playoff game in Western New York this year. Sunday’s victory over the San Francisco 49ers reminded the nation of the importance of home field advantage, as Buffalo took advantage of the West Coast team in the snow and looked slick doing it.

If there was one criticism of the Bills’ performance, it would be their inability to consistently stop the run. Before leaving the game with a knee injury, 49ers running back Christian McCaffrey appeared unstoppable on the ground, running for 53 yards on just seven carries. They also gave backup running back Jordan Mason another 78 yards on 13 carries. While it’s difficult to overly criticize the run defense in this game (it’s difficult to gain traction in the snow), Buffalo’s inability to stop the run has caused them problems in the past, most notably in defeat In Week 4 against the Baltimore Ravens, Derrick Henry ran for 199 yards and a touchdown on 24 carries. The next two weeks will continue to test Buffalo’s front four as they have showdowns with Kyren Williams of the Los Angeles Rams and a double date with Jahmyr Gibbs and David Montgomery of the Detroit Lions, arguably the best running back tandem the NFL.
