Michigan has gone back to its roots. The 17th-ranked Wolverines open their season Saturday at home against Central Michigan. On offense, Michigan will look like it used to before former coach Rich Rodriguez implemented his spread scheme in 2008 and recruited smaller, quicker players during his three-season stint with college football's winningest program. Brady Hoke adapted to the talent he had the last two years, especially speedy quarterback Denard Robinson, even though it delayed installing the kind of traditional offense he wanted to use. With Robinson graduated and playing for the Jacksonville Jaguars, quarterback Devin Gardner will take more snaps under center and is expected to hand off a lot more to running backs such as Fitzgerald Toussaint.
