Door is open in AFC South for the Colts

INDIANAPOLIS -- The AFC South was supposed to belong to the Houston Texans this season. The Texans were supposed to take the next step in the playoffs by pushing Denver and New England. Some even called them Super Bowl contenders. The Colts were supposed to just close the gap some on the Texans.

But the Texans are struggling (they blew a 20-3 lead and lost to Seattle in overtime on Sunday) and Houston ESPN.com reporter Tania Ganguli is spending quite a bit of time writing about the struggles of quarterback Matt Schaub.

The Texans are 2-2 and looking up at the Colts and the Tennessee Titans -- yes the Titans -- in the division.

Speaking of the Titans, they took a substantial hit with quarterback Jake Locker going down with a hip injury. Locker could miss 4-8 weeks, sources told ESPN Insider Adam Schefter.

Locker’s unfortunate injury and Houston’s problems gives the Colts an opportunity to get some space in the division. It won’t be easy, though, because the Colts host the Seahawks (4-0) at Lucas Oil Stadium in Indianapolis on Sunday. The Colts also have to go on the road to play at San Diego and host undefeated Denver on Oct. 20. The Denver game is already going to be huge because Peyton Manning is returning to Indy, but can you imagine how big the game will be if the Broncos are still undefeated and the Colts only have one loss when they play each other?

The Titans have it worse than the Colts -- and I’m not just talking about Locker's injury. They’ve got three games against teams that should make the playoffs or be in contention for a spot late in the season.

It wasn't an accident that I didn't mention the Jacksonville Jaguars. They may not even win a game this season.
