Starters: LT Bryant McKinnie, LG Ben Grubbs, C Matt Birk, RG Marshal Yanda, RT Michael Oher. Backups: G-T Mark LeVoir, C Bryan Mattison, T Jah Reid. Comment: The Ravens chose to keep an extra defensive back (Chykie Brown) and defensive lineman (Michael McAdoo) by going with fewer offensive linemen than usual. Don't be surprised if the Ravens add another veteran interior lineman before the season opener. Although Mattison did an admirable job, it would be smart for the Ravens to upgrade there considering Birk isn't fully recovered from knee surgery last month.
