Defensive PPG Allowed (Excluding Garbage Time), 2007-2009

KEVIN C. COX/GETTY IMAGES

Recently, Slice of Life posted a front page article on defensive performance under Coach Saban. In it, he questioned why the 2010 defense is viewed as "disappointing" when statistically it wasn't that far off from the "fantastic" 2012 unit. 13isNext posited that "trash TDs" or "garbage time scores" accounted for the statistical difference; in essence, the points that the 2012 unit allowed that made it seem not much better than the 2010 unit occurred when the outcome of the game was no longer in question. I thought that was a valid hypothesis to test.

To do so, the first thing we'd have to figure out is how to define "garbage time". Football Outsiders uses the following definition:

The criteria for "garbage time" are as follows: a game is not within 28 points in the first quarter, 24 points in the second quarter, 21 points in the third quarter, or 16 points in the fourth quarter.

I would argue that we should count any score that occurs up until the game is no longer considered competitive, but consider a point "garbage" if scored during an uninterrupted span of "garbage time" (defined above) that lasts until the end of the game. I'd add that a 9+ point advantage in the final 2 minutes also constitutes "garbage time". If we stipulate the above, we are left with the following (excluding defensive and special teams scores)....
