Tennessee Volunteers head coach Josh Heupel has a checkered history with the University of Oklahoma. On one hand, it’s his alma mater, and Heupel has the distinction of being the last Sooners quarterback to lead the school to a National Title. On the other hand, after serving as Oklahoma’s offensive coordinator for four seasons, Heupel was let go by the university in January 2015, leaving a scar up until this week had yet to fully heal.
