Trying to evaluate an NFL team's regular prospects based on preseason results is a lot like using movie trailers to write movie reviews: Poor results are usually deadly accurate predictors of a team's season, while even the best preseason performances tell you very little about how good your favorite NFL team will be once the games start to matter (see the 2008 Lions who followed a 4-0 preseason with an 0-16 regular season).
That said, the NFL preseason still gives teams and their fans the best opportunity to evaluate rookies, work free agents into new systems, rearrange depth charts and figure out what issues still need to be addressed before the regular season starts—for most teams—on Sunday, September 9.
Now that NFL teams have played a couple of preseason games, we still have as many questions about the 32 franchises as we do answers.
We know that Ryan Tannehill—along with fellow top-10 NFL Draft picks Andrew Luck and Robert Griffin III—will get a chance to prove himself in Week 1. But we still don't know if Kevin Kolb will ever pan out in Arizona.
We know that Terrell Owens has earned one last shot at salvaging his NFL career, while Chad Johnson may have prematurely ended his.
NFL teams still have plenty of position battles left to settle, injured players who have yet to heal and game-changing performers who have yet to end holdouts. But based on what we know after the first three weeks of the preseason, here are the most up-to-date NFL Power Rankings heading into the 2012 regular season.
10. Detroit Lions
11. Chicago Bears
13. Denver Broncos
16. Dallas Cowboys
20. Buffalo Bills
21. Tennessee Titans
22. Seattle Seahawks
23. New York Jets
24. Oakland Raiders
25. Tampa Bay Buccaneers
27. St. Louis Rams
29. Miami Dolphins
31. Cleveland Browns
