Drew Mehringer is a former quarterback at Rice, once the passing game coordinator under Tom Herman at Texas for three seasons.
At Rutgers in 2016 he became the youngest player caller in the Power Five at 28. Trouble was, the Scarlet Knights were woeful, averaging 15.7 points a game that season, dead last in yards per play at 4.13, 0-9 in the Big Ten and 2-11 overall.
While that's not encouraging, it's mean and pointless to define anyone by the worst job they ever had. After injuries cut short his playing career, Mehringer worked as a grad assistant at Iowa State and then Ohio State, earning a master's degree in sports management.
