The Buffalo Bills continued their late-season surge with an impressive 31-10 victory over the Dallas Cowboys on Sunday. The Bills' dominant performance on the ground, led by second-year running back James Cook, propelled them to victory as they finished with a staggering 266 rushing yards compared to the Cowboys' 89. Cook had a monster outing, recording 179 rushing yards, a rushing touchdown, 42 receiving yards, and a touchdown catch. His impressive performance earned him the distinction of becoming just the fourth Buffalo player ever to achieve 200-plus scrimmage yards, a rushing touchdown, and a receiving touchdown in the same game.

With the win, the Bills improved their record to 8-6 and showcased their title-contending potential. Quarterback Josh Allen praised the team's complete effort, describing it as a "complete team win." The victory solidified the Bills' position as one of the AFC's teams to beat.

On the other hand, the Cowboys suffered a disappointing 10-31 loss to the Bills, putting a dent in their postseason hopes. After weeks of excellence, the Cowboys' offense struggled to find its rhythm, managing just 195 yards in total. The defeat highlighted the team's inconsistency on the road, where they hold a 3-4 record compared to their unbeaten home record.

In another exciting matchup, the San Francisco 49ers secured their spot in the playoffs with a commanding 45-29 victory over the Arizona Cardinals. Quarterback Brock Purdy showcased his exceptional skills, throwing for four touchdowns and solidifying his position as a strong contender for the NFL's 2023 Most Valuable Player (MVP) award. Purdy's performance marked his 13th career start with a 100-plus passer rating, trailing only Patrick Mahomes and Hall of Famer Kurt Warner for the most games with a 100-plus passer rating in a quarterback's first 20 starts.

Running back Christian McCaffrey provided valuable support to Purdy, finishing the game with 115 rushing yards, a rushing touchdown, and two receiving touchdowns. With their sixth consecutive win, the 49ers improved to 11-3 and cemented their position as favorites to claim the No. 1 seed in the NFC.

Meanwhile, veteran quarterback Joe Flacco led the Cleveland Browns to a dramatic fourth-quarter comeback victory over the Chicago Bears. Despite throwing three interceptions, Flacco was instrumental in guiding the Browns to a 20-17 win. His connection with wide receiver Amari Cooper for a 51-yard touchdown and his leadership in the game-winning drive showcased his resilience and ability to make critical plays under pressure. Flacco's contribution has revived the Browns' season, and they currently hold the fifth spot in the AFC playoff race with a 9-5 record.

Overall, Week 15 of the NFL season provided thrilling matchups and significant outcomes. The Bills, 49ers, and Browns emerged as key contenders, while the Cowboys faced a setback in their postseason aspirations. With the playoffs approaching, teams are fighting for their spots, and every game becomes crucial in determining their fate.
