When Andrew Luck decided Stanford needed to change its head football coach at an unusual time in late March, he turned to a familiar face.

Andrew Luck almost retired one year earlier. Entering the 2018 season -- his seventh with the Indianapolis Colts -- fresh off of a 2017 campaign spent on the sidelines due to a shoulder injury, Luck had serious questions about his future.

Luck was hired in November by new school President Jon Levin to rebuild Stanford's struggling football program after four straight seasons with a 3-9 record, including the last two with Troy Taylor in charge.
