The Raiders have worked out a restructured contract with RG Mike Brisiel, dropping his 2013 salary from $4.35 million to $1.35 million.
It sounds like a true pay cut as opposed to a salary cap move. Brisiel was signed specifically to play guard in former Raiders OC Greg Knapp's zone-blocking system. The zone scheme has since been scrapped, and Brisiel may return as a backup only in 2013. He would've been released without the restructuring.
