Imo, the fact that our rushing statistics divided by quality of defense was comparable between 2013 and 2009 was very telling. It means that CPJ was able to get comparable results from his rushing game while adjusting for his talent. It also suggests that the problems with our offense in 2013 were in the passing game.
Since someone brought up the 4th qtr, I thought I'd compare our rushing offense and defense for TD's and TD's allowed; Passing offense and defense TDs; and total offense and defense TDs in the 4th qtr.
Year/Rush/Pass/Total

2011 8, 5; .. 1, 10; . 9, 15
2012 10, 4; . 4, 8; . 14, 12

I know that this doesn't say anything about competition, but this quick and dirty comparison doesn't show an obvious problem
