Each week during the season Athlon Sports looks at the best and worst football teams in the NFL. Here are our NFL Power Rankings following Week 4 of the season.
1. Texans (4-0) Top-ranked defense makes Houston a problem.
2. Falcons (4-0) Matty Ice leads last-minute comeback over Carolina.

Two elite teams will be looking to avoid a 1-2 start when the Baltimore Ravens host the New England Patriots tonight at 8:20 p.m. EST on NBC. Much will be made about the heartbreaking nature of Baltimore’s AFC Championship Game loss in New England last season, but the reality is that both of these squads with Super Bowl aspirations need to rebound from excruciating losses last week.


Athlon Sports is counting down its 2012 NFL preseason Power Rankings with in-depth team previews, schedule analysis and more as the start of the NFL season draws near.
