In the summer of 2015, people salivated over Tim Drevno running the Michigan line.
“He’s taught us stuff we had no idea was even out there,” Kyle Kalis stated in 2015.
“If you like manball, there’s no better guy to have as your offensive coordinator,” wrote Brian Cook on MGoBlog.
Three years later, Jim Harbaugh forced Drevno to leave for USC, where he now coaches running backs. Enter Ed Warinner, most recently the O-Line guru at Minnesota, but most famously the architect of some deadly lines for Urban Meyer and the Buckeyes.
