With a new system being implemented, Knapp is counting on Brisiel, who played in a zone-blocking scheme in six years with the Houston Texans, to be an on-field coach.
"It's good if they have any questions," Brisiel said of his dual role. "I'm familiar with the scheme so they can bounce anything they've got to ask me, bounce it off me. I get to tell them a little bit and then we can go try it out on the field."
The Raiders signed Brisiel, 29, to a five-year, $20 million contract with $6.5 million in guarantees in March.
"As an offensive lineman we really have a good core (of) plays we run," Brisiel said. "Everything is kind of, I'm trying to explain this right, everything is based on a certain thing that we stick to. We stick to our base plays, but a lot of different formations and what not. Really, as an offensive lineman, our base mentality stays the same for most of the run plays."
