N.F.L. Week 9 Game Probabilities First, fifth, second, second, fourth and 31st. Those are the league rankings of the Patriots" net passing efficiency with Tom Brady at the helm since New England's record-breaking 2007 season. The Patriots currently rank second to last in the most important and most consistent of all facets of team performance. Only the Buccaneers trail the Patriots in this category. Personnel turnover, injuries and poor play have taken their toll on one of the most reliably effective offenses in recent memory. Despite their challenges, the Patriots defy the numbers with a winning record of 6-2, leading the A.F.C. East by two games. They host the Steelers this week, who are struggling in last place in the A.F.C. North at 2-5. Pittsburgh's defense ranks 26th in the league in yards allowed per play, and its offense is struggling to run the ball. The Steelers rank 29th in the league in running Success Rate - the proportion of running plays that result in an improved scoring potential. Only the Giants, the Jaguars and the Ravens rank behind the Steelers in running success. Based on all key facets of team performance, the Patriots have the edge in this one, but not by much.
