Ben Baldwin, the guy who tweeted this, is a really smart guy. For analytical work, he is top notch.
None of this tells me anything.
What is EPA based on? How is it calculated?
What is CPOE based on? How is it calculated?
I realize that the most simplistic statistics often don't tell the complete story, For example a high completion percentage does not mean much if the QB never throws the ball more than 5 yards. But in order to appreciate these new metrics I have to have some idea of where they come from.
