The unbeaten Houston Texans remain the number one team in the TSN.ca NFL Power Rankings, but this week's changes start in the second spot.
Though the Atlanta Falcons have yet to lose, they did get passed for second spot in the rankings by the San Francisco 49ers, who have left a path of destruction against AFC East opponents the last two weeks and it was enough for the Niners to overtake Atlanta, whose last couple wins have been by relatively close margins.
Surprisingly 4-1, the Minnesota Vikings have climbed into the Top 10, going from 16 to nine after last week's easy win over Tennessee.
The Indianapolis Colts knew that they would be better this season, expecting a significant upgrade with rookie Andrew Luck at quarterback, yet they were underdogs (by at least a touchdown) at home against Green Bay. No matter, as Luck and veteran wideout Reggie Wayne led the Colts to a comeback win over the Packers, raising the Colts' ranking from 26 to 21.
Last Thursday, the Arizona Cardinals not only suffered their first loss of the season, but they lost another running back to injury and the offensive line couldn't protect quarterback Kevin Kolb. As a result, the Cardinals slipped from eight to 12.
Buffalo has allowed 97 points over the last two games -- 90 points in the last six quarters -- and this defensive implosion has resulted in a fall from 18 to 26.
