Today marks the 10-year anniversary of the first piece I published at Football Outsiders -- in fact, the first public introduction of the Fremeau Efficiency Index to the world, or at least this corner of it. A few months after Aaron Schatz and I first struck up an initial conversation about taking a deeper dive with college football data, he invited me to write that guest column to open up that dialogue to this community. I remain grateful for that opportunity and for the feedback loop it opened with the community here to take FEI from where it began to where it is today.
