Thought this was pretty interesting. The scatter plot shows over the last decade (2007-2016) average points scored per offensive drive along with average points allowed per defensive drive. The size of the plot is determined by a teams SOS. A teams wins are also listed.
Bama & OSU are the most dominate defenses while remaining in the top tier of points scored per drive.
The better defensive teams (right side of graph) generally have more wins. Teams on the right typically have >70 wins. Teams on the left typically have <70 wins. Teams in the upper right quadrant have >80 wins.
Most Wins: Bama (110), OSU (108) and Oklahoma (101)
Michigan & Notre Dame have essentially the same stats and wins. They are just to the right of Nebraska.
