Promise and potential can only go so far. Sooner or later, Michigan Wolverines running backs will either prove that they can advance their collective ground game or further demonstrate their need for more in the backfield.
The 2015 season will be a test in that regard, and the results will be solely based on the performances of Derrick Green, De’Veon Smith and Ty Isaac, along with those from running backs coach Tyrone Wheatley’s mixture of fullbacks and halfbacks.
Known for power-oriented offenses, head coach Jim Harbaugh seems intent on quickly developing a ground-and-pound technique rarely seen lately in Ann Arbor.
