also, finally somebody compiled points per drive, offensive and defensive (which many of us have argued is really the only stat that matters, as if filters out biases for big plays or passing or running or whatever)

Columns OPD and DPD are of interest. The stat filters out clock kills and garbage time. It also looks like bowls are not included. It also looks like it's not SOS adjusted. That said, it's a good stat.
Here are GT's relevant ranks
Year, Offensive Rank, Defensive Rank
2016, 32, 71
2015, 85, 80
2014, 4, 93
2013, 49, 79
2012, 18, 84
2011, 17, 81
2010, 55, 66
Soooooooo..... these numbers are not SOS adjusted, but they're not pretty. Yes, GT has to go against some tough offenses, but so does everybody else.
Perhaps a marginal improvement for Roof last year? It was the best performance of his time at GT, and maybe we could say that particularly in the second half of the season things improved?
I sort of think regardless, this is his "up or out" year. He has a full cycle of "his guys" that have been recruited by him, trained under him, and worked with him their entire careers. Every dude on that defense today is "his guy". Either he can produce with his guys, or he cannot. If GT is in the 50's this year in DPD, I think he's a keeper. You can maybe expect marginal improvement from there, as his recruiting successes build, but if you don't see that jump this year, I doubt it's going to happen.
