Each week, Football Outsiders takes a look at every game on the NFL schedule with a mix of interesting numbers and in-depth statistical analysis. Much of the analysis is based on DVOA, which takes every single play during the season and compares it to the league average based on situation and opponent. DVOA and Football Outsiders' other advanced stats are explained here.

According to Football Outsiders' stats, Houston's Steve Slaton leads all running backs in receiving value (144 DYAR, or Defense-adjusted Yards Above Replacement) but is dead last in rushing value (minus-146 DYAR).
