Brady Hoke once described offensive guard Kalis as “a road grader,” a description he uses to describe the large, mobile lineman he favors to power his running game. But at this point, the Wolverines need their interior offensive line to be “a road block” against defenders pressuring quarterback Devin Gardner. Give Gardner time and he is an amazing playmaker. Future opponents are taking note of how to shut down him down. And for now, all roads to accomplish that run through the middle of the Wolverines offensive line.
