Since work was so slow today, I thought I'd look post again and look at the correlation factor between each of the stats provided on pro-football-reference.com.
Here is the list of most correlated passing stats with wins from the past two years. Note the closer to 1 or -1, the closer to completely correlated you are.

Y/A is the second most important raw data point, with TD% at the top. As expected, passing statistics are not completely correlated with victory total - Defense and Running make up the last .31 of the correlation coefficient.
Interestingly, this data does suggest that 70% of your team's outcome is based on your passing game (passer rating). Finally some data to back up what we knew all along.
Total yards are barely more correlated than total attempts - which it think is fascinating.
