If the Chicago Bears want to be a running team, they need to get consistent and competent play from the offensive line. Racking up 165.5 yards per game on the ground through 2 preseason games (3rd best in the NFL) is great, but it's also being done by, and against, 2nd and 3rd stringers, and guys that will be among the first wave of cuts on September 1st.
The interior of the Bears' line seems solid with left guard Matt Slauson, center Will Montgomery and right guard Kyle Long, but offensive tackle has become a problem.
