NFL power rankings, Week 4: 49ers right in the middle sounds about right

Normally on Tuesday I put together a rundown of NFL power rankings, looking at what some sites around the Internet are posting. I will add those in later today, but I thought I would take a stab at my own power rankings. One upside to posting these for the first time now is I am not locked into my preseason rankings that leave some teams undervalued and some teams overvalued. I am sure I am still under- and over-valuing teams, but it is at least based on what I think I am seeing now.

I don't really have a specific philosophy in putting these together. I consider which teams have beaten each other, and if the rankings are close between them, the winner of the head-to-head matchup gets the edge. As we get later in the season, early season matchups will hold less value, but only three weeks in, a head-to-head win is worth a little more for rankings purposes.

I am a big fan of what the Bengals are doing, but I do still have them below both the Seahawks and Broncos. The Seahawks one loss came at San Diego, while the Broncos one loss came at Seattle. I don't think either team has done enough to deserve a move down. The Seahawks would have opened the season as my No. 1 because they are the defending champions. And while they have shown some flaws, they are still the top team until I see them slip a bit more.

For teams that have not played each other, generally I ask myself if team A beat team B if they met on a neutral field. An example of that would be the Bills and Patriots. I really liked the Bills heading into Week 3, and then they sort of crapped the bed against the Chargers. The Bills are still a solid team in my mind, but I just don't know that I see them beating the Patriots. And this might be an example of me overvaluing the Patriots. They have not been overly impressive thus far, with wins over the Raiders and Vikings, and a loss at the Dolphins. Are they still coasting on reputation, or will they improve as the season moves on?

I ranked the 49ers at No. 15, and I think that is pretty fitting. This is a 1-2 team that could be anywhere from 3-0 to 0-3 at this point. They are a talented team, and I think they can turn it around. And yet, the question marks have thrown us for a loop. Sitting them right in the middle seems right.

What do you think? Am I off my rocker with my assessment of the NFL through three weeks? Who have I overvalued, and who have I undervalued?
