And if the interception is run back for a touchdown,
that counts the same as the interception is run back for one yard.
And we know that yards per pass attempt is the most important statistic, and
completion percentage just really for team performance.
And completion percentage just doesn't really correlate well with team
performance after you adjust for yards per pass attempt.
You could run a regression to show that.
So if a quarterback reading is purporting to show how a quarterback helps a team,
or how good a team's passing offense is, I don't think it does the job.
And we go to Brian Burke's great site, advancedfootballanalytics.com in a few
videos, I think we'll see a better way to rate quarterbacks.
And I should mention ESPN has a total QBR,
which we're not ready quite to understand yet, but which really tries to
address the shortcomings in the NFL's quarterback rating.
And we may talk a little bit about that, but first we have
to talk about the concept of states in football and then the value of the state.
Because that's really the key to the concept of expected points,
which is really the key to understanding football at any level,
from Pop Warner or Pee Wee football to the great NFL.
