The Chicago Bears continued their steady climb in ESPN.com's NFL Power Rankings for Week 13.
As shaky as Chicago once appeared, there's no denying the Bears' revival. Their victory over Michael Vick and the Philadelphia Eagles helped move them into the No. 7 spot, up from No. 12 last week and No. 17 the week before. The Bears were ranked sixth heading into Week 4.
The Atlanta Falcons held onto the top spot with their close victory over Green Bay. The Packers and Bears were tied at No. 7, but Chicago won the tiebreaker based on head-to-head results. The NFC North rivals play again in Week 17.
And now, a closer look at the rankings heading into Week 13 ...

For download: An Excel file -- available here -- showing how each voter voted this week and in past weeks.
The worksheet labeled "sked" shows remaining schedule strengths based on current power rankings.
The Bengals, Bears and Cowboys each play a league-high four games against teams currently ranked in the top 10. The Colts, Broncos, Chiefs and Cardinals play none. The Bengals' remaining opponents average a 9.5 ranking, highest in the league. The Cardinals' opponents average a league-low 26.2.
The Steelers' remaining opponents have 2.5 median victories this season, the lowest figure in the league. The team does play two teams ranked in the top 10, however.
The file also includes a "powerflaws" sheet pointing out potential flaws in voters' thinking by showing how many higher-ranked opponents each team defeated this season. For example, the Titans and Texans have defeated a league-high four teams currently ranked higher than them. The Bills are the only team ranked lower than 14th without at least one victory over a higher-ranked team.
A quick primer on the "powerflaws" sheet:
Column Y features team rankings.
Column Z shows how many times a team has defeated higher-ranked teams.
Change the rankings in column Y as you see fit.
Re-sort column Y in ascending order (1 to 32) using the standard Excel pull-down menu atop the column.
The information in column Z, which reflects potential ranking errors, will change (with the adjusted total highlighted in yellow atop the column).
The lower the figure in that yellow box, the fewer conflicts.
