ANN ARBOR -- Michigan begins spring practice with plenty of questions surrounding its offensive line.
More for the tackles than inside, and it sounds like the Wolverines already have the interior figured out.
Speaking to reporters Friday after Michigan's first practice of the spring, head coach Jim Harbaugh detailed the plan for the center and guard positions heading into 2018.
"There's really proven players inside," Harbaugh said. "Cesar (Ruiz) is going to center, and he'll be competing there."
It's unclear at this point who else will compete there, but expect Ruiz, who will be a sophomore and started six games at right guard in 2017, to lock down that job early on.
