Overview: The ten-year veteran was once again a key piece to the Raiders offensive line, playing at both right tackle and left guard when rookie lineman Gabe Jackson went down with a leg injury. The Raiders honored Barnes with another one-year extension in November, worth up to $2 million. The versatile offensive lineman has proven that he can be counted on at a variety of positions, and certainly looks to be a key piece of depth as the Raiders move forward.
