Offensive line: C

If the Ravens are to establish a winning streak, the offensive line has to become more consistent and keep Flacco upright. If left guard Ben Grubbs (pictured) remains healthy, the Ravens might have a dominating left side with Grubbs and left tackle Bryant McKinnie. Right guard Marshal Yanda has played well, and right tackle Michael Oher has improved in the past two games. Center Matt Birk is solid, but there are questions about his speed and if he can consistently make blocks into the second level. Baltimore Sun photo by Gene Sweeney Jr.
