Michael Oher has found his comfort zone with the Ravens. Entrenched at right tackle, Oher is a key component of a Ravens offensive line that enters training camp far more settled than last season. Bryant McKinnie is re-signed and back at left tackle, and he reported to minicamp focused and in shape. That meant Oher could remain at right tackle, where he performed so effectively during the Ravens’ Super Bowl run. Now in his fifth season with the Ravens, Oher has developed into the solid offensive lineman the Ravens expected when they drafted him in the first round (No. 23 overall) in 2009. Oher is entering the final year of his contract at age 27, and he could be in line for an extension in the near future. The Ravens want to keep a stable unit in front of franchise quarterback Joe Flacco. Despite their numerous offseason changes, the Ravens return four of their five starters up front. Flacco feels confident he will have the protection he needs, and Oher is part of the reason.
