Serena and Matt preview the Michigan offense position by position and bring it all together with the unavoidable overarching question: With possibly the best offensive line in the country (again), definitely the best running back tandem in the country (again), and a returning quarterback who's not only the best in the Big Ten but has functionally no ceiling, is this the year the offense goes from "very good" to "truly elite?" And perhaps just as importantly, is "truly elite" actually necessary for Michigan to win the whole damn thing?
