After two weeks of football, the Houston Texans remain one of seven undefeated teams in the NFL. None of those teams currently reside in the AFC South, meaning Houston has a game lead on both the Jaguars and the Titans (and a two-game lead on the Colts) early in the season.
Of those teams, the only one that has shown it could be a problem for the Texans is Tennessee, who exploited a depleted Baltimore secondary with Kenny Britt. The Jaguars got absolutely destroyed by the Jets, which wouldn't be a problem if Luke McCown didn't look so terrible at quarterback. The Colts lost a battle of bad teams with the Browns to fall to 0-2.
Speaking of the Jets, the AFC East has three of those undefeated teams with the Patriots and Jets both at 2-0, as expected. The unexpected third team is the Buffalo Bills, who won a wild one with Oakland Sunday. The other undefeated teams are the Packers, the Lions and the Washington Redskins.
Six other teams are still winless. You could have guessed Seattle, Kansas City and Indianapolis might start out 0-2 while Carolina is only surprising due to how well its played through two weeks of the season. Both Minnesota and Miami are also winless, but showed that they're probably better teams than that. The Rams might have been better if not beset by all manner of injuries through two weeks.
