My Take

Theo Epstein is the kind of baseball genius who makes you rethink what "front office" even means. He became the Boston Red Sox's general manager at just 28 — the youngest in MLB history at the time — and promptly ended an 86-year championship drought with the 2004 World Series title. Then, as if that weren't enough, he moved to Chicago and did the impossible again: snapping the Cubs' 108-year curse with the 2016 World Series win. Two franchises, two legendary droughts, one guy. Yale-educated, analytically sharp but never losing sight of the human element in roster building, Epstein basically rewrote the playbook for modern baseball operations. Time naming him to their 100 Most Influential People in 2017 felt less like recognition and more like catching up to something that was already obvious.
