HOUSTON -- Just take a glance at the Houston Texans' remaining schedule and it's obvious how difficult it is.

Two undefeated teams and three members of the strong AFC East remain.

Aaron Schatz from Football Outsiders used teams' DVOA (defense-adjusted value over average) to determine which teams have the most difficult schedules.

Houston ranks fifth, with the average team expected to win 46 percent of the Texans' remaining games. By contrast, an average team would have been expected to win 53 percent of the Texans' games up to now. But he Texans are 3-5, with wins over the Jaguars, Buccaneers and Titans. They lost to the Chiefs, Panthers, Falcons, Colts and Dolphins.

More from Schatz: "The issue isn't the AFC South, because Houston has already had one game against each division rival. But the rest of the Texans' non-division schedule gets much tougher after the bye week. First, they have to face the undefeated Bengals in Cincinnati. Then three of the next four games are against the AFC East: home against the Jets and Saints, then a trip to Buffalo and finally Week 14 back home against the Patriots."

Right now the Texans are tied with the Colts for first place in the AFC South. After their bye week this week, it will take significant improvement if they hope to stay there.

And there's more bad news. The Colts have the fifth-easiest remaining schedule.
