Just saw this post on Reddit by BoMcCready on the team performance over the history of college football.  He created an interactive infographic in tableau which, I have to say, is pretty freaking awesome.  Here's the link:

There is a dropdown menu in the upper right corner where you can select different metrics to display.  Something fun to play around with while we wait for the season to start.
