Vittorio Tafur of The San Francisco Chronicle profiles Raiders starting center Samson Satele.
"Sammy's a hard worker, a very hard worker," Campbell said. "A lot of people don't appreciate what he brings to our team. People say he's too small, but he fight his butt off against guys who are 6-5. He's strong and he's fast and can get out on screens."
Wisniewski will be starting at guard alongside Satele in Denver on Sept. 12.
"Sammy's becoming a leader on the offensive line, and he and I have great communication with each other, pointing out blitzes and making sure we're on the same page," Campbell said.
