The offensive line can road grade
Good teams can run the football when they have to. Jim Harbaugh talked about how the best teams, like Georgia, can run the ball, even when the other team knows it's coming.
That's essentially how Michigan won the national title. It could do that to others, but they couldn't do that to the Wolverines.
The nine-play drive to milk the final six minutes off the clock, holding a narrow lead, was big-time. Blake Frazier needs work in pass protection. That's true across the board, but this offensive line has three redshirt freshman.
When you think about the development of Frazier, Jake Guarnera, and Andrew Sprague, it's exciting. Nathan Efobi is another starting-caliber player. Don't forget about Evan Link, Andrew Babalola or Ty Haywood.
The offensive line is in great shape. That was a concern earlier this season, but despite some ups and downs, the Wolverines have rushed for at least 175 yards in all five Big Ten wins.
