25. Jon Embree
Embree’s time as a head coach, in college, was brief. But, certainly worthy of making this list. The former Colorado star had a golden opportunity to lead his former school to greatness early last decade. Instead, Embree went 4-21 in two seasons while in charge of the Buffaloes. The good news for Embree, he’s managed to earn a living as an NFL assistant coach, currently employed as the tight ends coach with San Francisco.
