It is time for a matchup between two glass eating, road grading, and people mauling units. As the San Francisco 49ers outstanding offensive line prepares to face the Baltimore Ravens powerful defensive line. The 49ers may have the best offensive line in football, but the Ravens have Haloti Ngata, Paul Kruger, and Terrell Suggs. Pro-Bowlers Joe Staley and Mike Iupati anchor the 49ers offensive line, but center Johnathan Goodwin deserves just as much credit. Goodwin will see Ngata at times, but mostly will see defensive tackles Ma’ake Kemoeatu and Terrance Cody. Kemoeatu and Cody have been little more than space occupiers this year, and represent a hindrance to the Ravens rushing defense.
