Nice try. Incorrect defensive rankings.
Nice try? Incorrect? He's using a different statistic than you are and he was clear as day about it. Nothing underhanded or wrong about it.
It's the conventional way. If you don't like that, go with scoring defense. Still 2 to 1 Clemson.
All conventional means is that it's the way it's traditionally been done. It doesn't mean better. Things evolve and change. I mean do you honestly think that YPG and PPG are the best metrics of defensive performance? I'd say they're pretty poor.
