Justin Fuente rose quickly through the coaching ranks to become the head coach of the Memphis Tigers by age 36, and of the Virginia Tech Hokies by age 40. Fuente, a former Oklahoma Sooners and Murray State quarterback, cut his teeth as the QB coach at Illinois State. It took Fuente only three seasons to be promoted to offensive coordinator at ISU. In 2007, Fuente moved up to the Power 5 as the running backs coach at TCU, and was promoted to co-OC in 2009.
Fuente became the head coach at Memphis in 2012.
