I'm not involved with putting the rankings together, but it seems to give teams more credit for their 2009 performance then I would expect. For example, the Bears are ranked No. 15 despite a 2-0 record and coming off a good road win. I know it's not too impressive to see QB Jay Cutler pad his stats against the Lions "secondary", and the Cowboys win is just one game, but I would give them a little more credit.
In a way that makes the list great. It's so subjective. There are eight teams with a record of 2-0, and three of them are ranked at No. 15 or lower on the list. With two 0-2 teams in the top 11.
