What I have heard from the Big Ten Network, Jimbo, and Dierdorf is that this years' Michigan Offensive Line was the best that they have had in 20 years. Either two things are correct in assessing this statement. #1: Michigan's Offensive Line has been mediocre for 20 years, or #2: Michigan State's Defensive Front 7 is the better than every Michigan Offensive Line for the past 20 years.
