Okay, I took another look at footballoutsiders.com data for team efficiency. Football Outsiders historically featured two measurements of efficiency: Brian Fremeau's Fremeau Efficiency Index (FEI) and Bill Connelly's S&P+. FEI focuses on scoring success per meaningful possession (not clock-kill or game-out-of-reach possessions) and adjusts for strength of opponents. S&P+ calculates a measure of success rate (yards vs yards needed with respect to down) per play as well as points per play which it augments with some measure of drive success.
They calculate each of these independently for offense and defense which are then combined for a team ranking, FEI including a measure for special teams.
Starting in 2009 (though they've made numbers available for earlier years), they've combined the results of these statistical measures of efficiency to produce F/+ statistic for Offense, Defense and Special Teams which when summed results in the basis for their "official" rankings.
I took their results for the last six years (2008 - 2013) and pasted them into a spread sheet. I then averaged the F/+ ratings for all FBS teams (including the new ones). I then calculated the rank of each team for each 6-yr average F/+ as well as the 6-yr average for the total S&P+ and FEI.
Alabama was #1 in everything but special teams F/+ where they were 13.
As I may have posted here before, by this measure, GT has had #16 Offense, over the last 6 years. Yes that includes 2009 but it also includes 2010. Over these same 6 years, Navy had the #27 Offense. When you consider the recruiting-rankings for GT and Navy, I think these efficiency rankings are a pretty good vindication that our offensive scheme is sound.
In comparison, our 6-yr average of Def F/+ ranks at 57, which is right where we were ranked last year. Our D F/+ has basically hung in between -3% to 3% while the best D F/+ are around 22-25%.
