Being able to run the ball well and stop the run -- in other words, running the ball better than your opponent (YPC) -- has very little to do with winning in the NFL. The team that passes the ball better almost always wins.
In our games this season, the team that has passed the ball better is 6-0, while the team that has rushed the ball better is 1-5. The Titans' running backs averaged 6.6 YPC against us, Zac Stacy averaged 5.6, the Saints' backs averaged 8.2, Arian Foster averaged 6.8, and Marshawn Lynch averaged 6.1 -- and all of their teams lost. As good as DeMarco Murray has been, we aren't 5-1 if we don't pass the ball better than our opponent in each of our past five games.
