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.
This group has grown to 12 teams at the halfway mark. There's been a lot of movement up and down over the past month, but the real tests are still to come. Half of these teams won't be here come December.
No one is quite sure what to make of these teams yet. The potential is there, but their status remains in flux.
With the exception of OAK, every one of these teams has a winning record against teams below them, but a losing record against the contenders and pretenders. If you are a fan of these teams--temper expectations down the stretch.
None of these teams should be on prime-time for the rest of the season. It would be an insult to every football-loving fan.
