Power rankings are good to have, but they only tell you where teams sit in relation to one another in the overall scheme of things. A team lower in rank could easily defeat a team above it if they matchup well with them--something to keep in mind when evaluating weekend games.
As expected the cream eventually rose to the top. These four teams are the last teams to remain as true contenders heading into the playoffs based on their weighted regular season accomplishments. All of these teams not only had solid campaigns statistically, but won most of their big games during the season.
The pretender group has doubled since last month as teams settle into their rightful positions. These teams have enough to pull off a big win, but you are playing with fire if you bet on any of these teams to win the Super Bowl. Among this group, SF is the only team with a winning record in tough games during the regular season.
There were a lot of teams that moved in and out of this group to close out the year. All of these teams have the ability to make the playoffs next season if they can improve in key areas. Organizational stability and ability will be the difference between who rises and falls.
Not much to say about this group. The number of teams that finished in the bottom-third grew over the last month of the season. 16 games isn't a great sample size to evaluate teams, but it's pretty safe to say that none of these teams deserve a prime-time game next year.
