The NFC West is at the top of ESPN's NFL Football Power Index after Week 15.

The Arizona Cardinals remained No. 1 in FPI after a dominant 40-17 win over the Philadelphia Eagles on Sunday night. The Cardinals' FPI rating increased by over a point this week, and they are now a full point better than any other team on a neutral field, according to FPI.

The team that is directly behind the Cardinals in FPI is also directly behind them in the NFC West, as the Seattle Seahawks jump to No. 2. The Seahawks had an offensive efficiency of 91.8 in their 30-13 win over the Cleveland Browns, their third-highest in a game this season.

Though the New England Patriots fell one spot to No. 3, they are still by far the best team in the AFC, according to FPI. The Patriots would be favored by a point and a half over the next-best AFC team on a neutral field. The three teams fighting for the final two wild-card spots in the AFC are all ranked in the top 10 of FPI this week.

The biggest drop after Week 15? The Indianapolis Colts, who fell eight spots to No. 23 after losing to the Houston Texans in Indianapolis for the first time in NFL hisotry.

Among Week 16's games, two stand above the rest in terms of projected matchup quality. The Patriots take on the New York Jets (No. 9 in FPI) with a projected matchup quality of 88.4 (on a 0-to-100 scale). The Patriots can clinch home-field advantage throughout AFC playoffs with a win.

The Cardinals host the Green Bay Packers (No. 7 in FPI) with a projected matchup quality of 78.2. Arizona clinches a first-round bye with a win, while the Packers can clinch the NFC North win a win and a Minnesota Vikings loss.
