I can't pretend to know a ton about the more technical details of football. There's an embarrassing amount of nomenclature and general knowledge that, when I hear it from actual ball-knowers, I kind of just bob my head along with and silently pray that nobody directly quizzes me on the finer details of Cover 2 or whatever.
But on the other hand, I've been doing this Eleven Warriors thing for a while now, and through sheer osmosis I think that I have developed an innate sense of when the football vibes are on, and when they are off.
